Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan
yang liang » wang liang, yan liang, yang yang
di rene » di rete, dr rene, i rene
tian li » tan li, kian lia
li rong » yi rong, li cong, li song
rong su » rong yu, cong sun, jeong su
erence » terence, terrence

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yang guang) OR (yang liang)) ((di rene) OR (di erence)) tian li rong su ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yang guang) OR (yang liang)) ((di rene) OR (di erence)) tian li rong su ;*.
