Excuse me, is Erkang Pharmaceutical a big company? What does it mainly do?

As far as I know, Erkang Pharmaceutical is one of the largest professional pharmaceutical excipients manufacturers in China, and it is also a listed company, which can explain the strength of their enterprises. Secondly, Erkang Pharmaceutical has authorized patents 167, including domestic patents 157 and overseas patents 10. What the company produces is still very reliable.
