Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhieu tang » chieu sang, hieu lang, nhiet nang
hanh trang » thanh trung, canh tranh, hanh trinh
luong cong » dung cong, trong cong, cong cong
trang dap » trang doan, trang va, trang ha
dap luong » dai luong, da luong, do luong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than tap » toan tap, han tap, phan tap

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 ((chieu xanh) OR (nhieu tang)) - hanh trang dap luong cong dan than tap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (nhieu tang)) - hanh trang dap luong cong dan than tap*.
