Perhaps you should try some spelling variations:
liang ying » liang liying, zhang ying, jiang yajing
huang ying » huang jing, huang ting, huang yang
yang juan » yang jun, huang juan, jiang juan
juan rene » juan meng, juan rana
dang hadi » dang hai
pang can » pang jun, kang ca, pang kin
lung can » hung cam

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: ((liang ying) OR (huang ying)) yang juan rene ((pang can) OR (lung can)) dang hadi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((liang ying) OR (huang ying)) yang juan rene ((pang can) or (lung can)) dang hadi ;~".
• Adding a wildcard symbol may retrieve word variants: ((liang ying) OR (huang ying)) yang juan rene ((pang can) or (lung can)) dang hadi ;*.
