Perhaps you should try some spelling variations:
wang liang » wang yang
amin shang » amin hong, anming zhang
gene tang » gene bank
tang amin » tang min
shang hai » shang kai, dang hai, chang ha
yang hua » wang hua, yang hui, ying hua
yang jui » yang judy, yang di, yang xi

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: wang liang ((yang hua) OR (((yang jui) OR (yang (judy OR july))))) gene tang amin shang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ((yang hua) or (((yang jui) or (yang (judy OR july))))) gene tang amin shang hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ((yang hua) or (((yang jui) or (yang (judy OR july))))) gene tang amin shang hai ;*.
