Perhaps you should try some spelling variations:
thieu xanh » hieu manh, thien anh, thien danh
chieu xanh » chieu sach, chieu sang, chieu tinh
thong cong » trong cong, tong cong, thong thong
manh cua » doanh cua
cong tan » cong tac, cong san, cong thanh
tran cau » tran chau, toan cau, ran cau
ban cua » ban quan

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: toc ((thieu xanh) OR (chieu xanh)) - hanh ((manh cua) OR (ban cua)) thong cong tan tran cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu xanh) or (chieu xanh)) - hanh ((manh cua) OR (ban cua)) thong cong tan tran cau~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu xanh) or (chieu xanh)) - hanh ((manh cua) OR (ban cua)) thong cong tan tran cau*.
