What about Shanghai Toujing Life Science and Technology Co., Ltd.?

Touzhong is a very good R&D company, and its boss has a technical background and is very nice. Because of leading technology and high gross profit, it has grown very fast in recent years. I have cooperated with Beijing for many years and watched this enterprise grow. The employee turnover rate is not high, and the core employees have options. The company is a big taxpayer, just ask Zhangjiang Management Committee.
