Perhaps you should try some spelling variations:
vang chuan » zhang chuan, van thuan, vang cua
chieu xanh » chieu sach, chieu sang, chieu tinh
hien xanh » hien hanh, hien nhanh, hien khanh
hang cong » dang cong, hang nong, bang cong
anh mang » hanh mang, anh bang, anh dang
mang cua » manh cua, dung cua, ban cua
chuan ha » chuan he, quan ha, chuan bi

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 ((hien xanh) OR (chieu xanh)) - anh mang cua ((hang cong) OR (han tong)) vang chuan ha~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) OR (chieu xanh)) - anh mang cua ((hang cong) or (han tong)) vang chuan ha~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) OR (chieu xanh)) - anh mang cua ((hang cong) or (han tong)) vang chuan ha*.
