Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
ho chieu » theo chieu, hoc thieu, doi chieu
sinh cua » dinh cuu, sinh va
manh cua » doanh cua, ban cua
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan cau » 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: ho chieu xanh - hanh ((sinh cua) OR (manh cua)) thuong ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((sinh cua) OR (manh cua)) thuong ((cong dan) or (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((sinh cua) OR (manh cua)) thuong ((cong dan) or (cong tan)) toan cau*.
