Perhaps you should try some spelling variations:
song ming » song bing, gong min, jong min
tan yong » tan hong, tan yang, tan ying
tan kong » tan hong
colin xu » colin c, colin _
song min » gong min, jong min, song jin
long du » long do, long run, long did
long d » long do, long _, long 2

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: liang ((tan yong) OR (tan kong)) colin xu ((song min) OR (song ming)) ((long du) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "liang ((tan yong) OR (tan kong)) colin xu ((song min) or (song ming)) ((long du) or (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: liang ((tan yong) OR (tan kong)) colin xu ((song min) or (song ming)) ((long du) or (long d)) ;*.
