Perhaps you should try some spelling variations:
cong thanh » dong thanh, cong trinh, cong tan
thanh toan » thanh hoa, thanh san, tinh toan
doi chieu » doc hieu, doi chi, mot chieu
thong cua » thong quan, thong tu, huong cua
hang cong » dang cong, hang nong, bang cong
ho chieu » theo chieu, hoc thieu, mot chieu
manh cua » doanh cua, ban cua
toan ban » van ban

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) OR (doi chieu)) xanh - hanh ((thong cua) OR (manh cua)) hang cong thanh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) xanh - hanh ((thong cua) or (manh cua)) hang cong thanh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) xanh - hanh ((thong cua) or (manh cua)) hang cong thanh toan ban*.
