Perhaps you should try some spelling variations:
trinh thuat » trinh luat, trinh thiet, trinh thuc
thieu xanh » chieu xanh, hieu manh, thien anh
hanh trinh » canh tranh, hanh chinh
hung luong » dung luong, hang luong, hung cuong
hung vuong » hoang vuong
hoc thieu » toc thieu, hoc hien
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap

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 trinh thuat ((hung luong) OR (hung vuong)) dan than cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh trinh thuat ((hung luong) or (hung vuong)) dan than cau*.
