Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
cong thanh » dong thanh, cong trinh, cong tan
thanh toan » thanh hoa, thanh san, tinh toan
tieu xanh » chieu xanh, dieu hanh, tien anh
tieu danh » dieu danh, tiep danh, thien danh
trung cap » truong cao
toan tap » toan ban

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: theo ((tieu xanh) OR (tieu danh)) - thanh ((trung cap) OR (trung tam)) nhung cong thanh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) OR (tieu danh)) - thanh ((trung cap) or (trung tam)) nhung cong thanh toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) OR (tieu danh)) - thanh ((trung cap) or (trung tam)) nhung cong thanh toan tap*.
