Perhaps you should try some spelling variations:
tcanh tinh » thanh tinh, nhanh tinh, manh tinh
canh tinh » manh tinh, canh tranh, nhanh tinh
hanh tinh » hanh trinh, nhanh tinh, thanh tinh
trong lam » trong cac, trong ca, trong san
chao chu » cho chu, cua chu, cao cho
chu tinh » chau tinh, chua tinh, cuu tinh
cua dung » cua dang, cua dong, qua dung
lam toan » lam tan, lap toan, tam toan
toan ban » van ban

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: chao chu tinh - ((canh tinh) OR (((tcanh tinh) OR (hanh tinh)))) cua dung trong lam toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chao chu tinh - ((canh tinh) or (((tcanh tinh) OR (hanh tinh)))) cua dung trong lam toan ban~".
• Adding a wildcard symbol may retrieve word variants: chao chu tinh - ((canh tinh) or (((tcanh tinh) OR (hanh tinh)))) cua dung trong lam toan ban*.
