Perhaps you should try some spelling variations:
truong thanh » truong tran, tran thanh, truong xuan
luong thanh » long thanh
yang liang » wang liang, yan liang, peng liang
yang yang » wang yang, wang yan
liang wei » xiang wei, zhang wei, wang wei
wong laid » wong lai, kong land
wei gene » e gene, i gene, iii gene

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 yang liang wei gene ((truong thanh) OR (luong thanh)) wong laid ;~.
• Adding a wildcard symbol may retrieve word variants: yang yang liang wei gene ((truong thanh) or (luong thanh)) wong laid ;*.
