Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, hang cong
hieu manh » chieu xanh, hieu nganh, dieu hanh
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
san than » sang than, san thanh, van than
ban than » ban thanh, van thanh, ban hang

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: ho ((hieu manh) OR (trieu tinh)) - thanh trung cua nhung cong ((san than) OR (ban than)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (trieu tinh)) - thanh trung cua nhung cong ((san than) OR (ban than)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho ((hieu manh) or (trieu tinh)) - thanh trung cua nhung cong ((san than) OR (ban than)) cao*.
