Perhaps you should try some spelling variations:
young woman » young women, younger women
zhang ping » zhang ming, zhang jing, zhang ting
ping yang » ping wang, ying yang, ping pong
young man » young men, young male, young mary
wong shiu » wong siu, cong shu, song shin
dong bin » dong sin, dong di, dann bin
di li » li 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: zhang ping yang di li ((young man) OR (young woman)) ((wong shiu) OR (dong bin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ping yang di li ((young man) OR (young woman)) ((wong shiu) or (dong bin)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang ping yang di li ((young man) OR (young woman)) ((wong shiu) or (dong bin)) ;*.
