Perhaps you should try some spelling variations:
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
ky sang » ky nang, ky dang, ky tang
sang ma » tang ma, nang ma, sang tao
hieu ve » hieu va, hieu van
truc va » thuc va, thuc vat, trung va
danh vi » hanh vi, dinh vi, danh di
ma hai » ta hai, va hai, xa hai
ve cac » va cac, vien cac
vi cua » vai cua, di cua
cua te » cua tu

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: su sach ky sang ma hai. hieu ve cac ((truc va) OR (duc va)) danh vi cua te~.
• Adding a wildcard symbol may retrieve word variants: su sach ky sang ma hai. hieu ve cac ((truc va) or (duc va)) danh vi cua te*.
