Why did Hainan Province send Gui Pei to Shanghai?

I would like to ask why Dr. Gui Pei from Hainan Province was sent to Shanghai Hospital for Gui Pei. The local law training hospital sent it to Shanghai hospital for law training for the following reasons:

It is because Shanghai, as one of the important medical centers in China, is rich in medical resources and has a high professional level.

By sending Dr. Gui Pei to Shanghai and other places for training, we can broaden our horizons and get in touch with more advanced medical equipment and treatment programs, improve the medical level and service quality, and promote the medical reform and development of medical undertakings in Hainan Province.
