Perhaps you should try some spelling variations:
liang zhi » liang zhu, wang zhi, liang li
sang minh » kang minah, anh minh, song ming
hua gene » human gene, a gene, hua ren
song min » song ming, gong min, jong min
cong hai » hong hai, dang hai, cong van
liang di » liang li, liang dan, liang wei
qiang li » liang li, qiang niu, ling li

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 di) OR (liang zhi))) OR (qiang li)) hua gene ((sang minh) OR (song min)) cong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((liang di) or (liang zhi))) or (qiang li)) hua gene ((sang minh) OR (song min)) cong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((liang di) or (liang zhi))) or (qiang li)) hua gene ((sang minh) OR (song min)) cong hai ;*.
