mean change » can change, urban change
teng start » tech start, team start
yang muxi » yang jui, yang xi, yang hui
muxi teng » mui teng
seen hui » she hui
hui yang » hui ying, du yang, h yang

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

• Performing a fuzzy search may retrieve terms with similar spellings: (wing or lang) ((yuan change) OR (mean change)) seen hui yang muxi teng start ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR lang) ((yuan change) OR (mean change)) seen hui yang muxi teng start ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wing or lang) ((yuan change) OR (mean change)) seen hui yang muxi teng start ;*".
