Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
thanh di » thanh doi, thanh de, thanh do
tu sach » thu sach, su sach, te 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
xuc van » duc van, luc van, vuc van
ma hoi » mai hoi, xa hoi, ma hoa
ve cai » va cai, ve tai, ve cau
ve cac » va cac, vien cac
di cua » dai cua, doi cua, de cua

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 sach ky sang ma hoi. hieu ((ve cai) OR (ve cac)) xuc van thanh di cua vat~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky sang ma hoi. hieu ((ve cai) or (ve cac)) xuc van thanh di cua vat*.
