Perhaps you should try some spelling variations:
thong cong » trong cong, tong cong, thong thong
theo chieu » ho chieu, theo chu, thi chieu
tang cua » hang cua, tang luan, thong cua
mang cua » manh cua, dung cua, ban cua
cong dan » cong san, cong tan, huong dan
dan khan » dan khanh, dan chan, dan than
khan cap » khan ap, than cap, khoan cam

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) OR (theo tieu)) xanh - anh ((tang cua) OR (mang cua)) thong cong dan khan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo tieu)) xanh - anh ((tang cua) or (mang cua)) thong cong dan khan cap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo tieu)) xanh - anh ((tang cua) or (mang cua)) thong cong dan khan cap*.
