Perhaps you should try some spelling variations:
thoi quyet » toi quyet, theo quyet, thoi quen
nhung tri » nhung bai, dung tri, nhung bi
quen vang » quan van, que lang, quen hanh
truc lap » truc va, tu lap
truc may » tren may, truc va
quan va » quan vi, quan ha, luan va
que van » qua van, quy van, quyet van

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 tri ((((quen vang) OR (quan va))) OR (que van)). thoi quyet ((truc lap) OR (truc may))~.
• Adding a wildcard symbol may retrieve word variants: nhung tri ((((quen vang) or (quan va))) or (que van)). thoi quyet ((truc lap) or (truc may))*.
