Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
dao van » do van, dang van
toc sac » toc sach, toc san, hoc sach
nang xa » nang x, lang xa, nang ma
ve cac » va cac, vien cac
sac ky » cac ky, sai ky
doi va » hoi va, noi va, dai va
ve ca » ve cai, ve cau, ve cua
di va » dai va, di vao, di vat

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: toc sac ky nang xa hoi. hieu ((ve ca) OR (ve cac)) dao van thanh ((di va) OR (doi va)) triet~.
• Adding a wildcard symbol may retrieve word variants: toc sac ky nang xa hoi. hieu ((ve ca) or (ve cac)) dao van thanh ((di va) or (doi va)) triet*.
