Perhaps you should try some spelling variations:
thang nguoi » thanh nguoi, thong nguoi, tang nguoi
xuat thang » xuat thong, xuan thang, xua thang
che chinh » te chinh
hanh hang » thanh hang, hang hang, hanh han
hang xuat » hoang xuan, san xuat, nang suat
ban than » ban thanh, van thanh, ban hanh
ban hang » ngan hang

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: che chinh sach - hanh hang xuat thang nguoi ((ban than) OR (ban hang)) man~.
• Adding a wildcard symbol may retrieve word variants: che chinh sach - hanh hang xuat thang nguoi ((ban than) or (ban hang)) man*.
