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 » que lang, quen hanh, quet lang
quan van » luan van, quan va, quan luan
truc lap » truc va, tu lap
truc may » tren may, truc va
que van » qua van, quy van, quyet van

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: nhung tri ((((quen vang) OR (quan van))) or (que van)). thoi quyet ((truc lap) or (truc may))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nhung tri ((((quen vang) OR (quan van))) OR (que van)). thoi quyet ((truc lap) OR (truc may)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "nhung tri ((((quen vang) OR (quan van))) or (que van)). thoi quyet ((truc lap) or (truc may))".
• Adding a wildcard symbol may retrieve word variants: nhung tri ((((quen vang) OR (quan van))) or (que van)). thoi quyet ((truc lap) or (truc may))*.
