Perhaps you should try some spelling variations:
ban hang » ngan hang
ve chat » va chat, van chat
va dinh » van dinh, va kinh, va tinh
cau tre » cau tren, cau treo, cau tra
ve cham » va cham, vu cham, ve chim
cai ky » cao ky, cac ky, cam ky
di cau » da cau, diem cau
tu cai » tu cac, tu can, tu bai
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu cai ky nang x hoi. hieu ((ve cham) OR (ve chat)) soc ((ban hang) or (va dinh)) di cau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu cai ky nang x hoi. hieu ((ve cham) OR (ve chat)) soc ((ban hang) OR (va dinh)) di cau tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cai ky nang x hoi. hieu ((ve cham) OR (ve chat)) soc ((ban hang) or (va dinh)) di cau tre*".
