Perhaps you should try some spelling variations:
ban thanh » ban hanh, ban hang
thuat tac » thuat tach, thuat tao, thuat tai
va thanh » gia thanh, va tinh, le thanh
lai cuoc » tai cuc, va cuoc, lai cua
cuoc tro » cac tro, cuoc o
va cham » va chat, va tham
tac ky » tac ke, cac ky, tap ky
va cam » va cac, va cao, va cai
x hoi » xa hoi, o hoi, x ho

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: thuat tac ky nang x hoi. lieu ((va cam) OR (va cham)) xuc ((va thanh) OR (ban thanh)) lai cuoc tro~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat tac ky nang x hoi. lieu ((va cam) or (va cham)) xuc ((va thanh) OR (ban thanh)) lai cuoc tro~".
• Adding a wildcard symbol may retrieve word variants: thuat tac ky nang x hoi. lieu ((va cam) or (va cham)) xuc ((va thanh) OR (ban thanh)) lai cuoc tro*.
