khong cong » thong cong, khong cang, khong con
mot chieu » doi chieu, ho chieu
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
doc hieu » toc thieu, hoc thieu, hoc hien

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: ((mot chieu) OR (doc hieu)) sang - hanh tinh cua ((khong cong) OR (chong cong)) anh tuan cau~.
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (doc hieu)) sang - hanh tinh cua ((khong cong) or (chong cong)) anh tuan cau*.
