Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
nhung cong » dung cong, hang cong, nhung don
thong cong » trong cong, tong cong, thong thong
hoc thieu » toc thieu, hoc hien
thi chien » thi hien, thi thien, thien chien
trinh cua » tinh cua, trinh luat, trinh quan
dan chan » dan gian, dan ca, van chat
chan ban » can ban, chat ban, chan nan

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) OR (thi chien)) xanh - hanh trinh cua ((nhung cong) OR (thong cong)) dan chan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (thi chien)) xanh - hanh trinh cua ((nhung cong) OR (thong cong)) dan chan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (thi chien)) xanh - hanh trinh cua ((nhung cong) OR (thong cong)) dan chan ban*.
