Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
hoc thieu » toc thieu, hoc hien
tran nang » tra nang, tran dang, tran quang
nang dong » nang song, lang dong, nang luong
dong cong » duong cong, dung cong, dang cong
manh toan » thanh toan, anh tuan
doi chi » doi khi

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 (doi chi)) xanh - thanh tran nang dong cong ((manh toan) OR (tinh toan)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chi)) xanh - thanh tran nang dong cong ((manh toan) OR (tinh toan)) tap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chi)) xanh - thanh tran nang dong cong ((manh toan) OR (tinh toan)) tap*.
