Perhaps you should try some spelling variations:
chan thuong » phan thuong, han thuong, hang thuong
thanh trung » thanh tung
thuong cong » thong cong, thuong con, thuong dong
trung chan » trung phan, trong chan, trung can
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, cong tan, huong dan
phan cau » phan cac, phan tu, phan lap
phan dau » phan tu, hang dau
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 chan thuong cong dan ((phan cau) OR (phan dau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chi) or (ho chieu)) xanh - thanh trung chan thuong cong dan ((phan cau) OR (phan dau))~".
• Adding a wildcard symbol may retrieve word variants: ((doi chi) or (ho chieu)) xanh - thanh trung chan thuong cong dan ((phan cau) OR (phan dau))*.
