Please go ahead, sir. Thank you, Irene. Thank you, everyone, for participating in Yatsen's fourth quarter and full year 2023 earnings conference call today. I would like to begin with a macro overview before delving into the details of our strategy and progress across our segments and brands. China's beauty market experienced a modest recovery in 2023. According to the adjusted data published by the National Bureau of Statistics of China, total retail sales of consumer goods grew by 8.3% year-over-year for the fourth quarter and 7.2% for the full year. Against this backdrop, total beauty retail sales were up 1% year-over-year for the fourth quarter and 5.1% for the full year. Online beauty sales patterns were mixed in 2023. Sales on Tmall decreased while sales on Douyin increased year-over-year for both the fourth quarter and the full year. We made solid progress this quarter amid a still-soft retail environment, returning to a growth trajectory as we executed our strategy transformation plan. Perfect Diary brand repositioning is also proceeding as intended. To pave the way for future growth, we remain focused on building strong brand equity through superior products and consumer satisfaction while continuing investments in brand building and R&D. Our total net revenue for the quarter beat our guidance, up 6.7% year-over-year. Net revenues from our skincare brands for the fourth quarter grew by 17.6% year-over-year. Our clinical and premium skincare brands, including Galénic, DR.WU, and Eve Lom, delivered another solid performance, recording a 23.4% year-over-year growth in combined net revenues and further elevating their contribution to total net revenues. Net revenues from Color Cosmetics brands declined slightly by 1.8% year-over-year for the fourth quarter. In terms of channel optimization, we continued to strategically close underperforming offline stores. As of the end of 2023, we operated 110 offline experience stores for the Perfect Diary brand as compared with 158 stores a year ago. Our two other color cosmetics brands, Little Ondine and Pink Bear, continued to resonate with their customers and recorded year-over-year revenue growth. Our fourth quarter gross margin improved to 73.7% from 71.1% for the prior year period, benefiting from higher gross margin products and more disciplined pricing and discount policies. Our net loss margin expanded to 46.1% for the fourth quarter, primarily attributable to an impairment of goodwill as well as increased investment in our brands. The goodwill impairment recorded in the fourth quarter represents the amount by which the carrying value of the Eve Lom reporting unit exceeded its fair value based on quantitative goodwill impairment test due to weaker operating results than expected at the time of acquisition. Despite challenges in the market environment and ongoing competition, we still see potential in the brand. For the full year 2023, our net loss margin was 22% as compared with 22.2% in 2022. Our non-GAAP net loss margin narrowed to 8.7% from 12.2% for the prior year period, a significant improvement that underscores our skills in balancing cost structure optimization with the need to grab market opportunities as we drive sustainable growth. Moving on to the brands and products, for our skincare brands, we maintained our focus on brand building and introduced efficient products to foster deeper connections with each brand's audience. Galénic recorded solid performance during the Double 11 Shopping Festival, ranking number 1 in the premium brightening serum category in terms of retail sales value on both Tmall and Douyin with its Pure Vitamin C Serum. The brand is also making progress on its Couture line, winning the Essence of the Year award at the Bazaar Beauty Awards 2023 for its Couture Secret d'Excellence active serum. DR.WU's Acne Research Fund announced its first batch of pioneering research projects at the 2023 National Congress of Cosmetic Dermatology in Shanghai. DR.WU continues to push boundaries in clinical acne research and the application of mandelic acid, propelling the fields of long-term development. Eve Lom opened its first offline store in southern China in January this year, bringing the brand's spa experience to a broader customer base. With respect to Color Cosmetics, Perfect Diary brand repositioning continues to gain traction among its target customers. 'Biolip' Essence Lipstick, the new Hero product we launched in September 2023, has been gaining market share in the lipstick category on both Tmall and Douyin. During Double 12, the newly launched lipstick made Perfect Diary the number one lipstick brand in terms of retail sales value on Douyin. Given this product line's potential, we expanded the series to include 'Biolip' Essence Lip Stain in 2023 and 'Biolip' Essence Matte Lipstick in February 2024, enriching offering for customers to experience its advanced formulation. Perfect Diary also recently launched its Multi-Peptide Essence Tone Up Cream, the brand's very first product integrating a wrinkle-reducing cream with a makeup primer and a natural foundation. Both Little Ondine and Pink Bear introduced new products during the quarter. Little Ondine's 'Little White' Eyeliner Pen won the Eye Color Award in the Color Cosmetics category at the Vogue Beauty Awards 2023, while Pink Bear's 'Fairy Dream' Eyeshadow brought home the C- Beauty Awards Color Development Award. Moving now to the R&D, R&D expenses as a percentage of revenues were 3.4% for the fourth quarter and 3.3% for the full year 2023. Over the past year, we have significantly enhanced our R&D capabilities under the leadership of our Chief Scientific Officer, establishing a comprehensive R&D framework and a clear strategy direction. The R&D team has developed iconic products, including Perfect Diary's 'Biolip' Essence Lipstick and Galénic's Vivifying Micro-encapsulated Essence. We also strengthened our R&D infrastructure by setting up our Shanghai R&D Center. Along with these efforts, we promoted innovation through industry-academia collaborations, including leading initiatives such as DR.WU's Acne Research Fund and Galénic's Dermatology Research Fund. Going forward, we remain committed to R&D investments to drive innovation and growth. So before I conclude, a brief update on our 2023 ESG performance. Yatsen's dedication to environmental and social responsibility and employee welfare is integral to our brand and future development. We published our second ESG report in 2023, highlighting our alignment with prevailing green development initiatives. Furthermore, we were honored to be recognized at China's 2023 DEI Employer Awards for our deep commitment to inclusion and employee welfare. To summarize, we are pleased with our return to growth in the fourth quarter and will remain focused on pursuing sustainable growth with innovation across our brands. With that, I will now turn the call over to our CFO, Donghao Yang, to discuss our financial performance. Thank you, everyone. Thank you, David. Hello, everyone.

Total net revenues for the fourth quarter of 2023 increased by 6.7% to RMB 1.07 billion from RMB 1.01 billion for the prior year period.

As a percentage of total net revenues, general and administrative expenses for the fourth quarter of 2023 decreased to 14.8% from 16.9% for the prior year period.

As a percentage of total net revenues, research and development expenses for the fourth quarter of 2023 increased to 3.4% from 2.5% for the prior year period.

Impairment of goodwill for the fourth quarter of 2023 was RMB 354 million as compared with nil in the prior year period. Impairment reported in this quarter represents the amount by which the carrying value of the Eve Lom reporting unit exceeded its fair value based on quantitative goodwill impairment test, primarily due to weaker operating results than expected at the time of acquisition.

Total net revenues for the full year of 2023 decreased by 7.9% to RMB 3.41 billion from RMB 3.71 billion for the prior year period, primarily attributable to the decline in net revenues from color cosmetics brands, partially offset by the increase in net revenues from skincare brands.

Gross margin for the full year of 2023 was 73.6% as compared with 68% for the prior year period.

These forecasts reflect our current and preliminary views on the market and operational conditions, which are subject to change. With that, I would like to open the call to Q&A. We will now begin the question-and-answer session. To ask a question, you may press star, then one on your touch-tone phone. If you are using a speakerphone, please pick up your handset before pressing the keys. If at any time your question has been addressed and you would like to withdraw your question, please press star, then two. For the benefit of all participants on today's call, if you wish to ask your question to management in Chinese, please immediately repeat your question in English. At this time, we will pause momentarily to assemble our roster. The first question today comes from Maggie Huang with CICC. Please go ahead. Well, thanks for taking my question. This is Maggie Huang from CICC. Firstly, congratulations on our revenue returning to growth and beating our guidance. And I have two questions. The first one is regarding Perfect Diary. We are glad to see the great performance of our new products like Essence Lipstick in Q4. So for this year, do you have a target revenue contribution from the new products, and how should we expect on the revenue growth and net margin of the brand Perfect Diary? That's my first question. And my second question is regarding Women's Day Shopping Festival. So how is the performance of our brand so far, and is that in line with our expectations? That's my question. Thank you. Thank you, Maggie. For your first question on the performance on Perfect Diary, since our launch of the Biolip Essence Lipstick, its performance has been trending up. So for example, last year, December, the new lipstick is ranking number two on both Tmall and Douyin. So it's performing well. And in terms of new product contribution to the brand, last quarter, so fourth quarter of 2023, is a little below 40%. And we believe this year it will trend up to about 50%. So that's for the new product. And you also asked about margin. So basically, for this new product launch and also the Perfect Diary's brand upgrade, we're seeing some good feedback and results so far. First of all, the gross margin is much higher for this new product compared to the old product. The brand's average selling price also increased a lot to around RMB 140-RMB 150 on both Tmall and Douyin. In terms of consumer profile, we're also attracting more customers with higher affordability and beauty standing in general. So that's for your question number one. Then for question number two regarding the Women's Day's performance so far, the Women's Day Shopping Festival already started. Looking at the overall market, the performance is relatively modest. So as a result, for our brands, we're also seeing a relatively steady growth. We are putting more resources and efforts for the bigger shopping festivals, for example, 618 and Double 11. Got it. That's very helpful. Thank you very much. I have no more questions. Thank you. This concludes our question-and-answer session. I would like to turn the conference back over to management for any closing remarks. Thank you once again for joining us today. If you have any further questions, please feel free to contact us at Yatsen directly or at Piacente Financial Communications. Our contact information for both IR in China and the U.S. can be found in today's press release. Thank you, and have a great day. The conference is now concluded. Thank you for attending today's presentation. You may now disconnect.
