Perhaps you should try some spelling variations:
qua than » qua thanh, qua tan, quan thanh
ban hang » ngan hang
qua phan » cua phan, quang phan, luan phan
ky dang » ky nang, ky danh
hang vi » hang va, hanh vi, hang di
soc ban » hoc ban, coc ban, so ban

va chat » van chat, va phat, cao chat
dang ha » dong ha, dung ha, lang ha
ha hoi » hoa hoi, ha noi, xa hoi
vi cua » vai cua, di cua
te cac » tu cac, ve cac, te cao

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: te cac ky dang ha hoi. hieu ((va chat) OR (((qua than) OR (qua phan)))) soc ban hang vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky dang ha hoi. hieu ((va chat) or (((qua than) OR (qua phan)))) soc ban hang vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te cac ky dang ha hoi. hieu ((va chat) or (((qua than) OR (qua phan)))) soc ban hang vi cua tre*.
