Mr. M2; Dr. Sun do not have a home in China any more because Mr. Sun's father die and his mother is too old to take care of him. Dr. Sun is better off in the USA since he has been here most of his life. It's not easy to be poor in China. In the USA you still can get free food and free hospital visit. Thank you for sharing.
he gave up his Chinese nationality and became US citizen. there is ni obligation of Chinese government to look after him. why don't you use US government to provide him with social warfare?
Even his own siblings is not interested to take home , China government has no obligation to help them as they had not been contributing to China during young age and paying no taxes , further more he had became an Americans.
