Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh trang » thanh trung, canh tranh, hanh trinh
hanh tung » thanh tung, manh tung, hanh dung
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 tung) OR (hanh trang)) va nhung cong ((manh toan) OR (dan than)) cao~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh tung) or (hanh trang)) va nhung cong ((manh toan) or (dan than)) cao*.
