Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
su triet » su viet, su tien, ve triet
thanh vi » hanh vi, thanh va, thanh ve
ve phan » va phan, ve phat, vi phan
su sach » so sach
lang xa » lang ha, dang xay, lang van
vu sach » vu bach, vu khach
ke phan » kenh phan, ke thang
y lang » o lang, _ lang, tay lang
do van » dao van, vo van, so van
vi su » va su, ve su, ki su

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: ((su sach) OR (vu sach)) y lang xa hoi. hieu ((ke phan) OR (ve phan)) do van thanh vi su triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) y lang xa hoi. hieu ((ke phan) or (ve phan)) do van thanh vi su triet~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) y lang xa hoi. hieu ((ke phan) or (ve phan)) do van thanh vi su triet*.
