Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
tuong dong » tuong duong, trong dong, cuong duong
trang cua » tranh cua, tang cua, thang cua
trung cua » truong cua, trung tuan, trung cap
ho chieu » theo chieu, hoc thieu, doi chieu
dong tac » cong tac, dong tai, dong bac
than cap » thanh lap, thanh cac, than cua
khan cap » khan ap, khoan cam, phan cac

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 ((trang cua) OR (trung cua)) tuong dong tac ((than cap) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh ((trang cua) OR (trung cua)) tuong dong tac ((than cap) or (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh ((trang cua) OR (trung cua)) tuong dong tac ((than cap) or (khan cap))*.
