Perhaps you should try some spelling variations:
vien cac » vien bach, vien dai, vien da
cua tre » cua te, cuu tre, cua triet
danh du » danh dau, danh tu, dinh du
sang ma » tang ma, nang ma, sang tao
va danh » va dinh, va dan, va hanh
du cua » duy cua, dau cua, dum cua
tuc va » thuc va, truc va, tuc xa
sac ky » sai ky
ma hoi » mai hoi, xa hoi, ma hoa

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 ((sac ky) OR (cac ky)) sang ma hoi. hieu ((va cac) OR (vien cac)) tuc va danh du cua tre~.
• Adding a wildcard symbol may retrieve word variants: vu ((sac ky) or (cac ky)) sang ma hoi. hieu ((va cac) or (vien cac)) tuc va danh du cua tre*.
