Perhaps you should try some spelling variations:
thanh tung » thanh cong
chong cong » cong cong, thong cong, cuong cong
hoc thieu » toc thieu, hoc hien
manh toan » thanh toan, anh tuan
ho chieu » theo chieu, doi chieu, mot chieu
co chong » co chang, co chung, co phong
tung co » trung co, dung co, tung ho

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)) sang - thanh tung co chong cong ((manh toan) OR (tinh toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) sang - thanh tung co chong cong ((manh toan) or (tinh toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) sang - thanh tung co chong cong ((manh toan) or (tinh toan)) cao*.
