Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
nhung cong » dung cong, thong cong, hang cong
hoc thieu » toc thieu, hoc hien
trang cua » tang cua, trung cua, thang cua
tranh cua » doanh cua, manh cua
dan toan » dan than, manh toan, xuan toan
van toan » van tuan, van tan, van thanh

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 ((trang cua) OR (tranh cua)) nhung cong ((dan toan) OR (van toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh ((trang cua) OR (tranh cua)) nhung cong ((dan toan) or (van toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh ((trang cua) OR (tranh cua)) nhung cong ((dan toan) or (van toan)) cao*.
