Perhaps you should try some spelling variations:
thong cong » tong cong, thong thong, phong chong
thanh toan » thanh hoa, thanh san, tinh toan
doi chieu » doc hieu, doi chi, mot chieu
manh hung » anh huong
ho chieu » theo chieu, hoc thieu, mot chieu
hung dap » hung dao, hung dai, hung dam
toan cao » toan ban, toan tap

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 - manh hung dap ((thong cong) OR (trong cong)) thanh toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - manh hung dap ((thong cong) OR (trong cong)) thanh toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - manh hung dap ((thong cong) OR (trong cong)) thanh toan cao*.
