yang yang » wang yang, wang yan
gene long » gene clone, gene one
yan wang » yuan wang, qian wang, yan liang
hua gene » human gene, a gene, hua ren
long han » long chain, long thanh, long haul
han mung » thanh mung, han heung, han kyung
mung sau » aung san, wong sau

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wai ((yan wang) OR (yang yang)) hua gene long han mung sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai ((yan wang) OR (yang yang)) hua gene long han mung sau ;*".
