Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
yang guang » yang yang, yan guan
than china » tuan china, han china, wuhan china
hui yang » hui ying, du yang, hui ping
long do » long d, long du, longer do
h yang » _ yang
2 long » a long, 3 long, 3.2 long

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: ((yang liang) OR (yang guang)) ((than china) OR (can china)) ((hui yang) OR (h yang)) 2 long do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang liang) or (yang guang)) ((than china) or (can china)) ((hui yang) OR (h yang)) 2 long do ;~".
• Adding a wildcard symbol may retrieve word variants: ((yang liang) or (yang guang)) ((than china) or (can china)) ((hui yang) OR (h yang)) 2 long do ;*.
