Perhaps you should try some spelling variations:
thuong cong » thong cong, thuong con, thuong dong
chiet tach » chieu sach
chieu tinh » trieu tinh, lieu tinh, chau tinh
tung tam » trung tam, vung tam, tuong tac
dung tam » duong tam, dung tai, dung lam
cong san » cong tac
san than » sang than, san thanh, ban than
than cap » khan cap, thanh lap, thanh cac

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chiet tach) or (chieu tinh)) - thanh ((tung tam) OR (dung tam)) thuong cong san than cap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chiet tach) OR (chieu tinh)) - thanh ((tung tam) OR (dung tam)) thuong cong san than cap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (chieu tinh)) - thanh ((tung tam) OR (dung tam)) thuong cong san than cap*".
