Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh tra, thanh tuan
thanh toan » thanh hoa, thanh san, tinh toan
hoc thieu » toc thieu, hoc hien
nang dong » nang song, lang dong, nang luong
dong cong » duong cong, dung cong, dang cong
cong manh » cong danh, duong manh, cong thanh
manh toan » anh tuan, tinh toan
toan tap » toan ban
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) OR (thanh toan)) nang dong cong manh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (doi chi)) xanh - ((thanh tran) OR (thanh toan)) nang dong cong manh toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (doi chi)) xanh - ((thanh tran) OR (thanh toan)) nang dong cong manh toan tap*.
