daun yang » du yang, tan yang, un yang
hong dong » hong kong, hong jong, hong hong
wing han » wing ian, wing tan, ing hans
han chen » han shen, chang chen, han chang
dan yang » tan yang, wang yang, yang yang
sin » sign, sind, skin

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: wing han chen jian ((dan yang) OR (daun yang)) hong dong sin ;~.
• Adding a wildcard symbol may retrieve word variants: wing han chen jian ((dan yang) or (daun yang)) hong dong sin ;*.
