Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh dung » thanh dung, anh dung, manh dung
hanh dong » anh dong, ha dong
cua nhung » va nhung
manh toan » thanh toan, anh tuan, tinh toan
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
dan than » dan chan, ban than, van than

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 xanh - ((hanh dung) OR (hanh dong)) cua nhung cong ((manh toan) OR (dan than)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh dung) OR (hanh dong)) cua nhung cong ((manh toan) or (dan than)) tap~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh dung) OR (hanh dong)) cua nhung cong ((manh toan) or (dan than)) tap*.
