Perhaps you should try some spelling variations:
yang cindy » yang mind
sang minh » kang minah, anh minh, song min
jeong 情 » jeong _, jeongui 情, jeong mi
wang nan » wang yan, wang dan, wang yang
wang ban » wang yan, wang dan, wang yang
yang jin » yang jie, yang jun, ying jin
a chen » ta chen, _ chen, n chen
yan a » can a, yan _, jan a

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 nan) OR (wang ban)) yan a chen ((((sang minh) OR (yang cindy))) OR (yang jin)) jeong 情 ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang nan) OR (wang ban)) yan a chen ((((sang minh) or (yang cindy))) or (yang jin)) jeong 情 ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang nan) OR (wang ban)) yan a chen ((((sang minh) or (yang cindy))) or (yang jin)) jeong 情 ;*.
