Perhaps you should try some spelling variations:
di terence » di erence, liu terence, _ terence
yang guang » yang yang, yan guan, yang liang
lang yang » wang yang, yang yang, lang lang
dr rene » der rent
li cong » li rong, li song, jiu cong
cong yu » hong yu, rong yu, chong yun
gan » gain, gang, ganz

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

• If you are trying to use Boolean operators, they must be ALL CAPS: lang yang guang ((dr rene) OR (di terence)) gan li cong yu ;~.
• Adding a wildcard symbol may retrieve word variants: lang yang guang ((dr rene) or (di terence)) gan li cong yu ;*.
