Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
trang cua » tranh cua, tang cua, trung cua
khi xanh » khia canh, thi hanh, thi anh
manh cua » doanh cua, ban cua
cong tan » cong tac, cong san, cong thanh
toan cau » toan ban, toan tap, toan tai
toan cao » toan ban, toan 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: doi khi xanh - hanh ((trang cua) OR (manh cua)) nhung cong tan ((toan cau) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: doi khi xanh - hanh ((trang cua) or (manh cua)) nhung cong tan ((toan cau) or (toan cao))*.
