What is the proportion of different types of packaging products of the company? What is the gross profit margin? With the implementation of new production capacity, how much percentage can the high-end packaging and testing part increase?

Changdian Technology: Hello, advanced packaging has become the company's main source of revenue, mainly from system-level packaging, flip-chip and wafer-level packaging. The company has not disclosed the specific revenue, gross profit margin and sales volume of each type of packaging separately. Please refer to the company's annual report for detailed disclosure. In 2021, nearly 2/3 of the company's capital expenditure was invested in capacity expansion related to advanced packaging. In the future, the proportion of the company's advanced packaging revenue will continue to increase. Thank you!
