Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » thong cong, hang cong, nhung don
hoc thieu » toc thieu, hoc hien
dung cong » dung trong
sang than » cang thang, dang thanh, sang tao
lan hanh » ban hanh, van hanh, lan anh
than cau » toan cau, phan cau, than cap
hanh va » hang va, hanh vi

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 - lan hanh va ((((nhung cong) OR (dung cong))) OR (trong cong)) sang than cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - lan hanh va ((((nhung cong) or (dung cong))) or (trong cong)) sang than cau*.
