Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhanh dung » hanh dung, nhanh hung, thanh dung
nhanh dong » hanh dong, nhanh chong, anh dong
cong thanh » dong thanh, cong trinh, cong tan
ho chieu » theo chieu, hoc thieu, doi chieu
van cong » van dong, van phong, phan cong
toan tai » doanh tai, toan ban, toan cao
toan tap » toan ban
cua van » cua ban, cua vat, cua dan

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 - ((nhanh dung) OR (nhanh dong)) cua van cong thanh ((toan tai) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((nhanh dung) OR (nhanh dong)) cua van cong thanh ((toan tai) or (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((nhanh dung) OR (nhanh dong)) cua van cong thanh ((toan tai) or (toan tap))*.
