Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
ho chieu » theo chieu, hoc thieu, doi chieu
manh cua » doanh cua, ban cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cao » toan ban, toan tap
hang ca » hang va, nang cao, hang tai

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: ho chieu xanh - hanh ((manh cua) OR (hang ca)) nhung ((cong dan) OR (cong tan)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((manh cua) or (hang ca)) nhung ((cong dan) OR (cong tan)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((manh cua) or (hang ca)) nhung ((cong dan) OR (cong tan)) toan cao*.
