Perhaps you should try some spelling variations:
liang tan » liang dan, wing tan
liang sun » liang dan, wing sun
yan yang » yang yang, yao yang, dan yang
yang hua » wang hua, yang hui, ying hua
hua gene » human gene, a gene, hua ren
hong sau » wong sau, hong paul, kong sar
wang » wing, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: (wang or wan) yan yang hua gene ((liang tan) OR (liang sun)) hong sau ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wan) yan yang hua gene ((liang tan) OR (liang sun)) hong sau ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan yang hua gene ((liang tan) OR (liang sun)) hong sau ;*".
