Perhaps you should try some spelling variations:
thuat tac » thuat tach, thuat tao, thuat tai
thanh lai » thanh hai, thanh lap, thanh loi
duoc tren » nuoc tren, thuoc tren, dung tren
va thanh » gia thanh, ban thanh, va tinh
lai duoc » lai cuoc, lam duoc, mai duoc
cao xuc » cao duc, cao suc, chat xuc
tac ky » tac ke, cac ky, tap ky
x hoi » xa hoi, x ho, 5 hoi
o hoi » co hoi, o hoc, o hai

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