Perhaps you should try some spelling variations:
di terrence » di erence, deal terrence
yang guang » yang yang, yan guan, yang liang
lang yang » wang yang, yang yang, lang lang
kim song » kim young, kim eung
dr rene » der rent
yi song » yi rong, jie song, jin song
li song » li cong, li rong, jie 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 yang guang ((dr rene) OR (di terrence)) tian ((((yi song) OR (li song))) OR (kim song)) yun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yang guang ((dr rene) or (di terrence)) tian ((((yi song) OR (li song))) or (kim song)) yun ;~".
• Adding a wildcard symbol may retrieve word variants: lang yang guang ((dr rene) or (di terrence)) tian ((((yi song) OR (li song))) or (kim song)) yun ;*.
