Perhaps you should try some spelling variations:
trinh xuat » trinh luat, trinh xuan, trich xuat
chu xanh » chu manh, chieu xanh, chua xang
tinh cua » trinh cua, sinh cua, tinh chat
cong van » cong vang, song van, cong tan
cong san » cong tac
toan cao » toan ban, toan tap
cho chu » cho thue

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 - hanh ((trinh xuat) OR (tinh cua)) trong ((cong van) OR (cong san)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho chu xanh - hanh ((trinh xuat) or (tinh cua)) trong ((cong van) OR (cong san)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: cho chu xanh - hanh ((trinh xuat) or (tinh cua)) trong ((cong van) OR (cong san)) toan cao*.
