Perhaps you should try some spelling variations:
chang minh » chang min, zhang ming, chan ming
base shen » base shear, base en
zhang zhi » zhong zhi, wang zhi, zhang dai
zhang wei » zhen wei
wang qin » wang lin, wang qiao, wang jing
qin wang » qian wang, liqin wang, ping wang
base she » base shear, based shm, base de

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 qin wang ((base shen) OR (base she)) chang minh ((zhang zhi) OR (zhang wei)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qin wang ((base shen) OR (base she)) chang minh ((zhang zhi) or (zhang wei)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang qin wang ((base shen) OR (base she)) chang minh ((zhang zhi) or (zhang wei)) ;*.
