Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
manh trung » thanh trung, manh hung, sinh trung
hoc thieu » toc thieu, hoc hien
manh tung » manh hung, thanh tung
trong van » trong cac
van tuan » van quan, van ban, anh tuan
tuan ban » tuan bang, toan ban, luan ban
ap dung » xay dung, van dung

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: hoc thieu xanh - ((manh trung) OR (manh tung)) ap dung trong van tuan ban~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((manh trung) or (manh tung)) ap dung trong van tuan ban*.
