Perhaps you should try some spelling variations:
nhung thoi » nhung thi, phung thi, nhung loi
quen vang » quan van, que van, que lang
noi tuong » doi tuong, noi tong, noi trong
tuong hoc » truong hoc, tuong ho, duong hoc
noi dung » hoc dung
dung hoc » dong hoc, dung thuoc, trung hoc
hoc moi » hoc noi
hoc mo » hoc mot, hoc mon, hoc ma

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: (( nhung thoi quen vang. noi dung hoc mo ) OR ( nhung thoi quen vang. noi tuong hoc moi ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thoi quen vang. noi dung hoc mo ) or ( nhung thoi quen vang. noi tuong hoc moi ))*.
