In 2022, the company's revenue grew by 5% year-on-year, while gross profit and net profit grew by 8.1% and 6.4% year-on-year respectively, which were higher than revenue growth. In addition, the amount of free cash flow was higher than net profit. Next, I will introduce our key financial performance. The company took several measures to strengthen cost control across the board, with the cost of revenue accounted for 88.6% of total revenue in 2022, which decreased by 0.4% point year-on-year. For direct personnel costs, we proactively controlled the total staff number, which led to a continuous decrease in direct personnel cost as a percentage of revenue.

In 2022, the company focused on efficiency improvement and strived to enhance operating efficiency. By elevating the value of business and controlling operating costs, gross profit margin stabilized and recovered. The company continued to increase its investment in R&D, which increased the R&D expenses as a percentage of revenue to 3.5%. However, SG&A expenses as a percentage of revenue excluding R&D expenses reduced to 6.4%. SG&A continues to be well under controlled. The above measures have improved the operating efficiency significantly with operating profit increased by 10.2% year-on-year. Net profit growth accelerated higher than revenue growth. In 2022, SMEs were under greater financial pressure due to the impact of the change in macro economy environment.
