dang hadi » dang hai
yana hua » tan hua, ya hua, yang hui
tuan hua » tan hua, tuan vu, yuan hui
yang le » yang li, yang jie, wang lei

• If you are trying to use Boolean operators, they must be ALL CAPS: wang handling ((((yana hua) OR (tuan hua))) OR (wang hua)) chen yang le dang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: wang handling ((((yana hua) or (tuan hua))) or (wang hua)) chen yang le dang hadi ;*.
