Perhaps you should try some spelling variations:
huang ying » huang jing, huang ting, huang yang
huang weng » huang cheng, huang jing, huang ting
ong cheng » hong cheng, zong cheng, ong chong
1 green » 2 green, 1 grenzen
4 green » 2 green
john n » john _, john c, john d
n siu » ng siu, _ siu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((huang weng) or (ong cheng))) or (huang ying)) can china ((1 green) OR (4 green)) john n siu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((huang weng) OR (ong cheng))) OR (huang ying)) can china ((1 green) OR (4 green)) john n siu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((huang weng) or (ong cheng))) or (huang ying)) can china ((1 green) OR (4 green)) john n siu ;*".
