Perhaps you should try some spelling variations:
thuong cong » thong cong, thuong con, thuong dong
chieu xanh » chieu sach, chieu sang, chieu tinh
trung tuan » trung thanh, trung tam, tran tuan
ho chieu » theo chieu, hoc thieu, doi chieu
dung cua » dung luan
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - thanh ((((dung cua) OR (dung cho))) OR (trung tuan)) thuong cong san than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - thanh ((((dung cua) OR (dung cho))) or (trung tuan)) thuong cong san than cap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - thanh ((((dung cua) OR (dung cho))) or (trung tuan)) thuong cong san than cap*.
