Perhaps you should try some spelling variations:
bach van » bach dan, bach dang, bach xuan
cach van » cac van, canh van, cach mang
truc va » thuc va, thuc vat, trung va
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
ve cau » ke cau, va cau, le cau
ve cac » va cac, vien cac
va anh » van anh, va danh, va hanh
anh te » anh tu, anh ta, anh ve
te cua » tue cua, le 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: su ((bach van) OR (cach van)) nang xa hoi. hieu ((ve cau) OR (ve cac)) truc va anh te cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((bach van) or (cach van)) nang xa hoi. hieu ((ve cau) OR (ve cac)) truc va anh te cua tre~".
• Adding a wildcard symbol may retrieve word variants: su ((bach van) or (cach van)) nang xa hoi. hieu ((ve cau) OR (ve cac)) truc va anh te cua tre*.
