Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
hanh mang » nhanh mang, hanh trang, nhanh lang
cong cong » cong dong, trong cong, dung cong
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
san toan » dan toan, manh toan, xuan toan
van toan » van tuan, van tan, van thanh

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: theo chu xanh - ((hanh mang) OR (hanh trinh)) cua cong cong ((san toan) OR (van toan)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - ((hanh mang) or (hanh trinh)) cua cong cong ((san toan) OR (van toan)) cao~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((hanh mang) or (hanh trinh)) cua cong cong ((san toan) OR (van toan)) cao*.
