Perhaps you should try some spelling variations:
hear gain » heat gain
liang dan » liang tan, king dan, liang sun
dang hadi » dang hai
wing tan » wing ian, liang tan, hong tan
can hear » can gear, can learn, can help
wang lin » wang li, wang qin, yang lin
yang xi » yang di, yang jui
yang yi » yang di, yang jui

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 tan) OR (liang dan)) can hear gain ((wang lin) OR (((yang xi) OR (yang yi)))) dang hadi ;~.
• Adding a wildcard symbol may retrieve word variants: ((wing tan) or (liang dan)) can hear gain ((wang lin) or (((yang xi) or (yang yi)))) dang hadi ;*.
