Perhaps you should try some spelling variations:
va thuat » ky thuat, ki thuat, va thuc
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, mang xa
danh vi » hanh vi, dinh vi, danh di
nang ma » tang ma, sang ma, nang cao
va danh » va dinh, va dan, va hanh
va cham » va chat, va tham
vi cua » vai cua, di cua
xuc va » duc va, tuc va, luc va
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky

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: tu san ky ((nang xa) OR (nang ma)) hoi. lieu ((va cham) OR (va thuat)) xuc va danh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky ((nang xa) OR (nang ma)) hoi. lieu ((va cham) or (va thuat)) xuc va danh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu san ky ((nang xa) OR (nang ma)) hoi. lieu ((va cham) or (va thuat)) xuc va danh vi cua tre*.
