Is there a listed company in Chengdu Freshman?

Yes, Chengdu Shengnuo Bio is located in Dayi, at No.258, Section 1 of Dayi Industrial Avenue. It was listed in June, 20021,and it is considered as a relatively qualified leading enterprise in the industry, mainly engaged in polypeptide drugs and preparations. Has it been established for more than 20 years? Some time ago, I saw a news report that Sanye was still developing COVID-19's specific drugs and medical beauty products.
