Perhaps you should try some spelling variations:
doanh thanh » danh thanh, doanh nhan, dinh thanh
thieu xanh » chieu xanh, hieu manh, thien anh
canh thanh » canh tranh, danh thanh, anh thanh
cong thanh » dong thanh, cong trinh, cong tan
hoc thieu » toc thieu, hoc hien
thanh qua » thanh quan, thanh qui, hanh qua
qua dung » quang dung, su dung, qua song
phan cau » phan dau, phan cac, phan tu

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 - canh thanh qua dung ((cong thanh) OR (doanh thanh)) phan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - canh thanh qua dung ((cong thanh) or (doanh thanh)) phan cau*.
