Perhaps you should try some spelling variations:
thanh trung » thanh tung
can thuong » chan thuong, han thuong, lan thuong
trung can » trung cap, trung van, trong can
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
phan cau » phan dau, phan cac, phan tu
doi chi » doi khi

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: ((doi chi) OR (ho chieu)) xanh - thanh trung can thuong ((cong dan) OR (cong tan)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chi) or (ho chieu)) xanh - thanh trung can thuong ((cong dan) OR (cong tan)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((doi chi) or (ho chieu)) xanh - thanh trung can thuong ((cong dan) OR (cong tan)) phan cau*.
