chang sing » change using, chang min, changes using
muang sing » huang jing, huang ting, huang ying
yan yuan » yan guan, fang yuan, nan yan

kong shu » cong shu, kong siu, tong shui

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: wan ((yang guang) OR (yan yuan)) bin chin ((chang sing) OR (muang sing)) kong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yang guang) or (yan yuan)) bin chin ((chang sing) OR (muang sing)) kong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((yang guang) or (yan yuan)) bin chin ((chang sing) OR (muang sing)) kong shu ;*.
