In a pharmaceutical company, you can exercise your personal ability and negotiation ability, learn a lot of experience, get to know many doctors and customers, pave the way for starting your own business in the future, and your salary is relatively stable. Working in a stem cell company is stressful, and the salary is not very stable and there is no guarantee. So it's slightly better in a pharmaceutical company than in a stem cell company.
Pharmaceutical companies are mainly engaged in the trade of medical treatment and medical devices, and will have certain distribution capacity and specialized logistics companies.
