Perhaps you should try some spelling variations:
hieu vien » hieu hien, hieu viec, thieu nien
van thanh » ban thanh, van tuan
vien cac » vien bach, vien dai, vien da
thanh di » thanh doi, thanh de, thanh do
sach ky » sach ty, sach kem, sach hay
nang xa » nang x, lang xa, nang ma
cac xuc » cam xuc, cac nuoc, chat xuc
xuc van » duc van, luc van, vuc van
sac ky » cac ky, sai ky
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: te ((((sach ky) OR (sach y))) OR (sac ky)) nang xa hoi. hieu vien cac xuc van thanh di cua vat~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((((sach ky) OR (sach y))) or (sac ky)) nang xa hoi. hieu vien cac xuc van thanh di cua vat~".
• Adding a wildcard symbol may retrieve word variants: te ((((sach ky) OR (sach y))) or (sac ky)) nang xa hoi. hieu vien cac xuc van thanh di cua vat*.
