Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
theo lieu » theo tieu, theo chieu, theo yeu
lieu tinh » trieu tinh, diep tinh, bien tinh
hanh tung » thanh tung, manh tung, hanh dung
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
dan toan » van toan, manh toan, xuan toan
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 lieu tinh - ((hanh tung) OR (hanh mang)) cua nhung cong ((dan toan) OR (dan than)) cao~.
• Adding a wildcard symbol may retrieve word variants: theo lieu tinh - ((hanh tung) or (hanh mang)) cua nhung cong ((dan toan) or (dan than)) cao*.
