Perhaps you should try some spelling variations:
jiang yajing » jiang liping, liang ying
liang liying » jiang liping, liang lilin, liang ying
doing hai » doing what, dang hai, doing a
wang qin » wang lin, wang qiao, wang jing
ii doing » ii ding, iv doing, ifc doing
yang ii » yang di, yang xi, yang yi

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 ((jiang yajing) OR (liang liying)) ((wang qin) OR (yang dean)) yang ii doing hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((jiang yajing) or (liang liying)) ((wang qin) or (yang dean)) yang ii doing hai ;*.
