hear gain » heat gain
yan liang » yang liang, wang liang, you liang
dang hadi » dang hai
can hear » can gear, can learn, can help

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: wenn woman can hear gain ((yan liang) OR (ying jin)) dang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: wenn woman can hear gain ((yan liang) or (ying jin)) dang hadi ;*.
