What is the consulting telephone number of China-Japan Friendship Hospital of Jilin University?

I want to talk to the dean myself. Shang Haijun is the safety director of Chinese and Japanese hospitals. His relatives sell breakfast in China and Japan and don't let others sell it. I asked his relatives to beat him today. Shang Haijun used his power to rob and kick other breakfast sellers. I have their videos, asking the dean and leaders of the Chinese and Japanese hospitals to let Shang Haijun give me an explanation.
