Executive Director, Mr. Gao Chunlei, and Chief Accountant, Mr. Hu Shaofeng. Now, around after this event, it's divided into two parts. Firstly, the management team will give you the results for 2023, and then we're going to have the Q&A session. Now, I'd like to give the floor to Chairman Zhang Zhiyong, who's going to give you a presentation on the overall performance of the company in 2023. Ladies and gentlemen, good afternoon. Welcome, and thank you for joining us for China Tower's 2023 Annual Results presentation. We'd like to express our gratitude to you for your long-term support and interest in China Tower. Today's presentation is divided into three parts. Firstly, I'm going to give you the overall performance of the company, and then for the specific performance, it's going to be taken over by Mr. Gao Chunlei. Then in terms of our financial performance, it's going to be presented by Mr. Hu Shaofeng. After our presentations, we would be very happy to answer any question you have. In terms of the overall performance of the company, for last year, the company proactively provided service and moved towards the strategic goals of Cyber Power, Digital China, and Dual Carbon. Fortified its position of one core and two wings, while continuously deepened the development in sharing and coordination. The overall results for the past year grew steadily. Specifically, our overall performance was excellent. Our operational performance achieved double-digit growth of 11%, and supported by multiple pillars, two-wings business revenue increased to 12.2% of the total operating revenue. So we have multi-revenue sources established. And our smart towers serving digital governance. At present, 217,000 telecom towers have been upgraded to digital towers. The company also accelerated technological innovation. The R&D investment increased by 38%. The company also shared its fruitful results with shareholders. The dividend payout increased by 15.7%. In terms of the key indicators in 2023, as you can see from the slide, the major indicators are listed here. The annual operating revenue reached CNY 94.01 billion, an increase of 2% year-over-year. Profit attributable to the owners of the company reached CNY 9.78 billion, up 11%. As of the end of 2023, the number of tenants reached 3.658 million, and the tenancy ratio was 1.79, up 0.05 from the end of last year. The cycle co-location level continued to increase. Due to the implementation of our policy, you can see our collocation rate continued to improve. You can see that five indicators are red, meaning continue to improve. There is one indicator, registered negative growth, and I believe this is of great concern to every one of you here. That is our operating cash flow. There seemed to be a negative growth. This is very much a result of the new round of pricing agreement and service agreements. So we need to upgrade and adjust the charging system, and we also need to verify data of all orders, and we need to negotiate new service standards. So the account receivable collection process was negatively affected, and the cash flow level was lower than that of the previous year. I'd say this slide was temporary because in Q4 last year, it's already recovering. In January and February, it's a positive growth trend again. For the management, we trust for the year 2024, the cash flow level will return to normal level. The drop last year is just a temporary thing. In terms of our one core and two wings business, I'd say each business segment maintained a very good development trend, as you can see from the table here, excluding the impact of the commercial pricing agreements, which is a very big item last year. Excluding the impact of the commercial pricing agreements because we have offered some discount as a result of the pricing agreement, operating revenue on a comparable basis was CNY 97.72 billion, up 6% from the previous year. It's a very healthy, very positive growth trend. In terms of other business, apart from our TSP business, the two-wings business also grew very well. It accounts for 87.4% of total revenue. Revenue from the two-wings business totaled CNY 11.50 billion, accounting for 12.2% of total revenue. That's after we excluding the impact of the commercial pricing agreements. So you can see that our revenue from the Two Wings business has continued to improve in terms of its share of our total revenue growth. For the TSP business, we continue to consolidate our leading position. We expand the 5G network penetration coverage and seize the opportunities arising at key counties, fully push forward the healthy development of the TSP business. On a comparable basis, the TSP business grew by 3.4%. In terms of our Two Wings business, we continue to enhance resource sharing. Last year, the company had built 586,000 5G base stations, up 9.5% year-over-year, achieving a historical high. We have cumulatively built 2.347 million 5G base stations, supporting China in leading the world in terms of 5G network deployment. So we are indeed the leading force in the development of 5G in China. In terms of DAS business, it's another growth engine for the company. The company continued to leverage its advantage in coordinated construction, innovative products, and service solutions to help satisfy the demand for 5G upgrading of existing DAS as well as expanding to the new DAS market. So our covered building area was up 37.3% year-on-year, reaching 10.15 billion square meters. Our subway and high-speed railway tunnels coverage was up 20.1% year-on-year, reaching 11,625 and 12,447 kilometers, respectively. So you can see the DAS coverage continued to expand. As for our two-wings business, firstly, if we look at the smart tower business, the company sees the opportunities in digital economy and digital social governance, rely on our plentiful mid to high point site resources and specialized operation advantages, while continuing to enhance its core capabilities in five areas of platform, data, algorithm, application, and operation. We also aim to build the differentiated advantages with this algorithm for mid to high point monitoring service, continuously transforming telecommunications towers to digital towers, as you can see from the slide. Now, we provide over 100 mid to high point algorithms. So with the plentiful scenario trainings, we are able to provide more than 100 mid to high point high precision algorithms. At the same time, we have established more than 1.3 million unique mid to high point databases. So our algorithm will be more and more precise. We'll have more and more data, and we'll be able to offer more value in the future. In terms of our energy business, our advantage has been shown in the recent years. We try to meet customer needs by accelerating the product innovation. We try to meet customer needs in terms of battery exchange and power backup. We try to upgrade battery exchange products and develop standardized products for power backup. Also, we accelerated the platform's upgrade and optimized our service systems to strengthen our service capabilities. At the same time, we enhanced the level of delicate management, optimized resource allocation. So we push forward battery exchange business. For traction battery, we have a power backup. So there is a cascade utilization of batteries. We have a much higher efficiency in our tower business. So for last year, our revenue from energy business achieved CNY 4.21 billion, which is a year-on-year increase of 31.7%. The business scale continued to expand rapidly. For last year, the company continued to expand its innovation-led development strategy, cultivated the new advantages in high-quality development through technological innovation. We centered around targeting the forefront of world technology, serving the main battlefields of the economy, fulfilling the production and operation needs, and meeting actual customer needs, production, and business needs. We focused on key areas such as AI, new energy, computing power networks, 5G-A, and 6G, and increased investment in scientific and technological innovation. We improved results output efficiency, empowered our technological advancement, and enhanced quality and efficiency. The annual R&D investment increased by 38%, with the application for invention patents increased by 47%, and the authorized invention patents increased by 2 times. The company also continued to optimize the technological innovation systems and mechanisms. It built a 4-in-one innovation system led by the headquarters and was also the first batch establishing 6 technological innovation centers in places such as Hangzhou. We used the full list of capability-level projects, resource allocation, and achievement transformation to drive technological innovation. The company is taking the lead in carrying out over 100 key scientific research projects to accelerate the formation of new quality productive forces. As you can see from the slide, the company continued to improve its operation and management capabilities. We can say, for last year as a whole, we firstly implemented various measures for the digital management of fund assets by carrying out intelligent operation maintenance, the one code for all single-site accounting system, and construction of the treasury system to improve digital operation capabilities. In addition, we deepened the incentive system of management-level employees by implementing specialized talent programs to stimulate the motivation within the company. Thirdly, we reformed innovation capability and deepened the sharing of existing resources with new tenants. Collocation rate reached 85%. We continued to enhance the sharing of social resources. Last year, 36.3% of new ground tower sites were constructed by utilizing social resources. So we improved the resource coordination and sharing capabilities of the company. Fourthly, we launched the collaborative development of the One Core and Two Wings strategy, driving the upgrade of telecommunications tower to Digital Tower. So through having power exchange cabinets to provide reverse power supply to base stations, we established a large-scale operation and maintenance system connecting all customers, access and maintenance, monitoring, and ordering dispatching to improve the collaborative development capability. Thus, we can lower costs and further improve efficiency. Our core or our Two Wings business, we can provide comprehensive support and service to our customers. So we utilize existing operation and maintenance systems to fully serve our One Core and Two Wings customers so that our operation and management costs can be greatly reduced. So as you can see, this year, in terms of our operating revenue and we have the impact of the new commercial pricing agreement, we still achieve an 11% growth in net profit. That's very much due to the improvement in our operation and management efficiency. The company also continues to improve its payout ratio. The company always attaches great importance to shareholder returns, and we maintain a proactive dividend policy so that our shareholders can share the fruits of the company's development. So considering the future development needs and our cash flow level, the board recommended the distribution of a final dividend of RMB 0.03739 per share for 2023, an increase of 15.7% year-on-year. The dividend payout ratio of distributable net profit is 75%. In the future, the company will continue to build on its development momentum, improve profitability, and create greater value for shareholders. The company actively practices corporate social responsibility and is committed to achieving a harmonious symbiosis with society and the environment. In terms of environmental protection, the company reduced duplicated investment construction in industry through co-sharing. Also, we try to save land and reduce carbon emissions through various initiatives. In terms of our social contribution, the company successfully fulfilled its high-quality communication service for major events, for example, Asian Games in Hangzhou and the Universiade in Chengdu. China Tower has provided important telecommunication support, and also, our emergency response in hazardous weather was also outstanding. In terms of corporate governance, we stick to the diversification of the board, and we utilize the rich experience of our board members. We try to implement high-quality corporate governance to ensure the interests of our shareholders. This is the last slide of mine. Looking to the future, we will achieve quality development through our strategic guidance. We will achieve upgrading and transformation. We will follow the development of emerging industries by deepening the implementation of Cyber Power, accelerating the upgrades of digitalization, transformation to green and low carbon with the ample room for the company's development. As you can see from the slide, the company will continue to implement the One Core and Two Wings strategic layout, reinforce our core competitiveness. We will fully leverage our edge and resource coordination and build reputation for unrivaled advantages in integrated costs, project delivery, and maintenance service, as well as low management risk, further consolidate our leading position in our TSP business. We will also specialize in smart tower business and enhance energy business, thus driving the high-quality development of the two wings business and enhance enterprise value in order to bring greater return to all shareholders through the healthy development of the company.
