Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
hanh tang » hanh trang, anh tang, hanh mang
kha dung » khoa dung, khao dung, nha dung
cong tap » cuong tap, cong tan, tong tap
cong tac » cong ty
doan cau » toan cau, doan dau, doan cap
ha dung » hai dung, nha dung, ha dong

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 tang ((ha dung) OR (kha dung)) ((cong tap) OR (cong tac)) doan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh tang ((ha dung) or (kha dung)) ((cong tap) OR (cong tac)) doan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh tang ((ha dung) or (kha dung)) ((cong tap) OR (cong tac)) doan cau*.
