Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
ban thanh » ban hanh, ban hang
thanh cau » thanh chau, thanh mau, nhanh cau
chu xanh » chu manh, chua xang, chuc danh
chung tu » thong tu
cong ban » cong bang, cong san, cong tan

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: cho ((chu xanh) OR (chieu xanh)) - nhanh ((chung tu) OR (chung cu)) nhung cong ban thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) OR (chieu xanh)) - nhanh ((chung tu) or (chung cu)) nhung cong ban thanh cau~".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) OR (chieu xanh)) - nhanh ((chung tu) or (chung cu)) nhung cong ban thanh cau*.
