Does the company make millimeter wave radar chips? How is the current sales of chip products?

NavInfo: Subsidiary Jiefa is a chip design company with offices in Hefei, Shenzhen, Wuhan, Shanghai and other places. It mainly produces IVI (infotainment and navigation) chips, MCU (body control) chips, audio amplifier chips and TPMS tire pressure chips, among which MCU chips can be used in millimeter wave radar modules. The company's infotainment and navigation chips are shipped in millions of pieces per year, and its in-vehicle MCU chips are shipped in tens of millions of pieces per year. The products are in short supply, and the chip sales are good. The sales of the four product lines have increased year-on-year to varying degrees. Thank you.
