Perhaps you should try some spelling variations:
hoc thieu » toc thieu, hoc hien
van phung » van hung, van chuong, van dung
van phong » van dong, hai phong
ho chieu » theo chieu, doi chieu, mot chieu
hanh tam » thanh tam, nhanh tam, hanh tram
cong san » cong tac
san hanh » san thanh, ban hanh, van hanh
hanh cao » hanh cac, hanh cat, hanh cad

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: ((ho chieu) OR (hoc thieu)) xanh - hanh tam ((van phung) OR (van phong)) cong san hanh cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) xanh - hanh tam ((van phung) or (van phong)) cong san hanh cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) xanh - hanh tam ((van phung) or (van phong)) cong san hanh cao*.
