Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh quan » tinh quang, trinh luat, trinh han
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
doi chieu » doc hieu, doi chi, mot chieu
ho chieu » theo chieu, hoc thieu, mot chieu
tan toan » tan tran, tap toan, van toan
toan tap » toan ban

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 (doi chieu)) xanh - hanh trinh quan ((nhung cong) OR (thong cong)) tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - hanh trinh quan ((nhung cong) OR (thong cong)) tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - hanh trinh quan ((nhung cong) OR (thong cong)) tan toan tap*.
