Perhaps you should try some spelling variations:
liu terence » muir terence
yang guang » yang yang, yang liang
yan guan » gan guan, yan yuan, yihan guan
song yun » song byung, chong yun, young yun
dr rene » der rent
tian li » tan li, kian lia
li song » li cong, li rong, kim song

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 ((yan guan) OR (yang guang)) ((dr rene) OR (liu terence)) tian li song yun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang ((yan guan) OR (yang guang)) ((dr rene) or (liu terence)) tian li song yun ;~".
• Adding a wildcard symbol may retrieve word variants: lang ((yan guan) OR (yang guang)) ((dr rene) or (liu terence)) tian li song yun ;*.
