Why didn't Hengrui recruit Hausen's people?

Although Hengrui Pharma and Haosen Pharmaceutical Co., Ltd. are husband-and-wife stores, they also have a competitive relationship. In the actual operation of enterprises, the existence of horizontal competition will inevitably make it impossible for related enterprises to compete on an equal footing in a fair market environment, so they cannot recruit people from the other company.

Hengruiduo focuses on research and development, while Haosen focuses on sales.
