Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hanh trang » thanh trung, canh tranh, hanh trinh
hoc thieu » toc thieu, hoc hien
cua khong » hua khong, cua phuong, cua thuong
cong tam » cong tac, cong tan, cong nam
phat cau » phan cau, phap cau, phat am
pha cau » phan cau, phap cau, pha cac

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 khong) OR (cua cong)) cong tam ((phat cau) OR (pha cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh trang ((cua khong) or (cua cong)) cong tam ((phat cau) OR (pha cau))~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - hanh trang ((cua khong) or (cua cong)) cong tam ((phat cau) OR (pha cau))*.
