Perhaps you should try some spelling variations:
tuong thong » thong thong, tuong tuong, tuong tong
thieu xanh » chieu xanh, hieu manh, thien anh
thanh dung » thanh duong, thanh tung, thanh hung
tong thong » thong thong, dong thong, cong thong
hoc thieu » toc thieu, hoc hien
hanh dung » anh dung, hanh dong, manh dung
tin toan » tinh toan, nin toan, trinh toan
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: hoc thieu xanh - ((hanh dung) OR (thanh dung)) luan ((tuong thong) OR (tong thong)) tin toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - ((hanh dung) OR (thanh dung)) luan ((tuong thong) or (tong thong)) tin toan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((hanh dung) OR (thanh dung)) luan ((tuong thong) or (tong thong)) tin toan cao*.
