Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
cua tre » cua te, cuu tre, cua triet
ky tang » ky nang, ky dang, kho tang
tang ma » mang may, tang van
ma khoi » mai khoi, ra khoi, xa khoi
ve cham » va cham, ve chat, vu cham
dinh vi » dinh ve, dinh viet, dinh tri
va dinh » van dinh, va kinh, va tinh
vi cua » vai cua, di cua
xuc va » duc va, tuc va, luc va
vu sai » vu hai, vu san, vu dai
sai ky » sac ky
ve cac » va cac

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: vu sai ky tang ma khoi. hieu ((ve cham) OR (((ve cac) OR (vien cac)))) xuc va dinh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sai ky tang ma khoi. hieu ((ve cham) or (((ve cac) OR (vien cac)))) xuc va dinh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sai ky tang ma khoi. hieu ((ve cham) or (((ve cac) OR (vien cac)))) xuc va dinh vi cua tre*.
