Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, hieu manh, thien anh
hoc thieu » toc thieu, hoc hien
quang cua » quan cua, quang tuan, dung cua
trong dan » trong dang, trong san, trong ban
trong tan » trong quan, trong cac, trong ca
thanh bac » nhanh bac, thanh bai, thanh san

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: hoc thieu xanh - tinh ((quang cua) OR (quang huy)) cong ((trong dan) OR (trong tan)) thanh bac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - tinh ((quang cua) or (quang huy)) cong ((trong dan) OR (trong tan)) thanh bac~".
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - tinh ((quang cua) or (quang huy)) cong ((trong dan) OR (trong tan)) thanh bac*.
