In 2006, Wang was among the first group of more than 10 oculists organized by Shandong provincial government to conduct free cataract extraction and intraocular lens implantation for over 300 patients in Shigatse. He was deeply touched by people's attitudes towards them.

"Their pure smiles, and the tears they couldn't hold back because they were so excited to be able to see the world again, deeply touched me. It made me feel that I should carry on the program to help more Tibetan people regain clear vision," says Wang.

Three years later, Wang, together with several other oculists, went to Tibet for the second time to provide free surgeries to 110 cataract patients in five counties. In addition, they went to primary schools to conduct eye checkups on students and taught them how to take care of their eyes.
