Perhaps you should try some spelling variations:
lei sheng » kwei sheng, wei shang, l.t sheng
wing ian » wing tan, twinn ian, wing sun
yang jie » yang di, yang jui, yang jun
yang jin » yang jun, ying jin, shang jin
wong siu » wong shiu, kong siu, wong sau
yang xi » yang di, yang jui
yang yi » yang di, yang jui
pan » plan, pain, puan

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ian pan lei sheng ((((((yang jie) OR (yang xi))) OR (yang jin))) OR (yang yi)) wong siu ;~".
• Adding a wildcard symbol may retrieve word variants: wing ian pan lei sheng ((((((yang jie) OR (yang xi))) OR (yang jin))) OR (yang yi)) wong siu ;*.
