What are the reasons for Le Kang's late marketing of Cangzhou Beichi Group Harbin Pharmaceutical Group? Is it reliable?

A group with a very good development platform. My friends have worked there for 10 years, and they are all local people in Cangzhou. If it had been closed long ago, they would not have worked in Cangzhou for more than 10 years. Yes, but it seems that an interview is needed! They are not selling directly, but promoting Harbin Pharmaceutical Company!
