Perhaps you should try some spelling variations:
phuong troi » phuong trong, huong toi, phuong tran
nhung thoi » nhung thi, phung thi, nhung loi
troi quyet » toi quyet
quen vang » quan van, que van, que lang
con duong » van duong
duong uoc » huong uoc, duong hoc, duong nguoc
doi tuong » moi truong, doi song
tuong hoc » truong hoc, tuong ho, duong hoc
hoc mo » hoc moi, hoc mot, hoc mon

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. con duong uoc mo ) OR ( phuong troi quyet van. doi tuong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung thoi quen vang. con duong uoc mo ) or ( phuong troi quyet van. doi tuong hoc mo ))*.
