Perhaps you should try some spelling variations:
liang yang » liang ying, wang yang, yang yang
zhang ying » zhang ming, zhang jing, zhang ping
song ming » song bing, gong min, jong min
song min » gong min, jong min, song jin
long do » long du, longer do, long ago
long d » long du, long _, long 2
li wu » l wu, yi wu, li ju

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: wang ((liang yang) OR (zhang ying)) li wu ((song ming) OR (song min)) ((long d) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang yang) or (zhang ying)) li wu ((song ming) or (song min)) ((long d) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang yang) or (zhang ying)) li wu ((song ming) or (song min)) ((long d) OR (long do)) ;*.
