Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
trong dong » trong cong, trong nong, trong dang
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
thanh cac » hanh cac, thanh bac, thanh ca
ho chieu » theo chieu, hoc thieu, doi chieu
dong tam » dong tai, dong nam, don tam
than cap » khan cap, thanh lap, than cua

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