Perhaps you should try some spelling variations:
trinh mung » trinh quang, thanh mung
long trinh » long trip, long thanh
yan liang » yang liang, wang liang, yan wang
you liang » you liangzhi
you xian » you can, you mean
mung lai » wong lai
li gene » i gene, iii gene, lof gene
l1 gene » 1 gene, 11 gene, a1 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 ((yan liang) OR (((you liang) OR (you xian)))) ((li gene) OR (l1 gene)) long trinh mung lai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((yan liang) or (((you liang) OR (you xian)))) ((li gene) or (l1 gene)) long trinh mung lai ;~".
• Adding a wildcard symbol may retrieve word variants: yang ((yan liang) or (((you liang) OR (you xian)))) ((li gene) or (l1 gene)) long trinh mung lai ;*.
