Perhaps you should try some spelling variations:
chua nang » chuc nang, chua xang, kha nang
hanh dung » thanh dung, anh dung, hanh dong
nang nong » nang song, hang nong, nang dong
vang toan » van toan, dang toan, quang toan
dung van » duong van, dung va, dang van
van nang » van quang, van ban, van dong
dan toan » van toan, dan than, manh toan
chu van » cuu van, chu han

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: theo ((chu van) OR (chua nang)) - hanh dung van nang nong ((vang toan) OR (dan toan)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chu van) or (chua nang)) - hanh dung van nang nong ((vang toan) or (dan toan)) cau*.
