Perhaps you should try some spelling variations:
thuat tac » thuat tach, thuat tao, thuat tai
thanh lai » thanh hai, thanh lap, thanh tai
thanh loi » thanh hoa, thanh hai, thanh lap
duoc tren » nuoc tren, thuoc tren, dung tren
va cao » va cac, va co, va bao
va dao » ca dao
tac ky » tac ke, cac ky, tap ky
xuc va » duc va, tuc va, luc va
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 cao) OR (va dao)) xuc va ((thanh lai) OR (thanh loi)) duoc tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat tac ky nang x hoi. lieu ((va cao) OR (va dao)) xuc va ((thanh lai) or (thanh loi)) duoc tren~".
• Adding a wildcard symbol may retrieve word variants: thuat tac ky nang x hoi. lieu ((va cao) OR (va dao)) xuc va ((thanh lai) or (thanh loi)) duoc tren*.
