Dear Mr. Secretary, does the company have semiconductor revenue? If yes, please don't hide it. How is the technical strength? How is the business? Who is the customer of the company in China? Please speak out loudly, okay?

Tianjue Technology: Hello, thank you for your attention to the company. The company completed the acquisition of 100% equity of Germany's MueTec in May 2021. MueTec has been focusing on optical dimension measurement of semiconductor front-end wafers for many years, covering multiple front-end process links. Its products are highly mature and its customers include many international mainstream semiconductor manufacturers. MueTec achieved operating income of 39.7085 million yuan from June to December 2021. At present, the relevant equipment of MueTec, a wholly-owned subsidiary of Tianjue Technology, and its shareholding company Suzhou Silicon Semiconductor can be used for the measurement and inspection of 65-90nm process node wafers. MueTec's products are mainly semiconductor front-end measurement equipment, and this part of the revenue is included in the visual measurement equipment products.
