Perhaps you should try some spelling variations:
hanh tranh » canh tranh, hanh trinh, hanh trang
hoc thieu » toc thieu, hoc hien
tranh van » tran van, trinh van, thanh van
nang cong » dang cong, bang cong, hang cong
manh toan » thanh toan, anh tuan, tinh toan
ho chieu » theo chieu, doi chieu, mot chieu
toan ban » van 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 (hoc thieu)) xanh - hanh tranh van ((nang cong) OR (nang song)) manh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) xanh - hanh tranh van ((nang cong) OR (nang song)) manh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - hanh tranh van ((nang cong) OR (nang song)) manh toan ban*.
