Perhaps you should try some spelling variations:
dang tay » dang xay, dung tay, dan tay
luu tre » luu tru, cuu tre, luy tre
soc van » hoc van, sac van, soc dan
ky dang » ky nang, ky danh
va tuan » van tuan, va toan, a tuan
va quan » van quan, tac quan, hai quan
vi luu » vi lua
oc van » hoc van, luoc van, quoc van
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
tay ho » tay co, tay o, tay khao

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 sac ky dang tay ho. hieu ((va tuan) OR (va quan)) ((soc van) OR (oc van)) hanh vi luu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky dang tay ho. hieu ((va tuan) or (va quan)) ((soc van) OR (oc van)) hanh vi luu tre~".
• Adding a wildcard symbol may retrieve word variants: te sac ky dang tay ho. hieu ((va tuan) or (va quan)) ((soc van) OR (oc van)) hanh vi luu tre*.
