Perhaps you should try some spelling variations:
yang using » yang jing, making using, change using
guan ming » yuan ming, kian ming, tuan minh
ming chih » ming shih, ming china, lin chih
hang sing » hang seng, muang sing, change using
yan guan » gan guan, yan yuan, yang guang
kong eiu » tonga eiu
wang » wing, wan

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 OR lang) yan guan ming chih ((hang sing) OR (yang using)) kong eiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan guan ming chih ((hang sing) OR (yang using)) kong eiu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yan guan ming chih ((hang sing) OR (yang using)) kong eiu ;*.
