Perhaps you should try some spelling variations:
peng liang » wang liang, yang liang, deng ziliang
hong thang » hoong chang, hong hong, hong tan
yang yang » wang yang, wang yan
long way » wrong way
long arm » long term
l1 gene » 1 gene, 11 gene, lof gene
a1 gene » a gene, 1 gene, 11 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: ((peng liang) OR (yang yang)) tan ((l1 gene) OR (a1 gene)) hong thang ((long way) OR (long arm)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((peng liang) or (yang yang)) tan ((l1 gene) OR (a1 gene)) hong thang ((long way) or (long arm)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((peng liang) or (yang yang)) tan ((l1 gene) OR (a1 gene)) hong thang ((long way) or (long arm)) ;*.
