Perhaps you should try some spelling variations:
nhanh thanh » phan thanh, nhanh tinh
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
thuy hang » thu hang, thuy hong, thuy hanh
hang cong » dang cong, hang nong, bang cong
cong san » cong tac
than cap » khan cap, thanh lap, thanh cac
han tap » han tai, toan tap, nhan tai

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: theo chieu xanh - nhanh thanh thuy hang cong san ((than cap) OR (han tap))~.
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - nhanh thanh thuy hang cong san ((than cap) or (han tap))*.
