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
sach vay » sach va, sach hay, sach nay
xuc van » duc van, luc van, xuc ban
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach y
sach 2 » sach y
va cam » va cham, va cac, va cao
vi su » va su, ve su, ki su

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((((sach v) OR (sach vay))) or (sach 2)) nang xa hoi. hieu va cam xuc van thanh vi su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((((sach v) OR (sach vay))) OR (sach 2)) nang xa hoi. hieu va cam xuc van thanh vi su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((((sach v) OR (sach vay))) or (sach 2)) nang xa hoi. hieu va cam xuc van thanh vi su triet".
• Adding a wildcard symbol may retrieve word variants: tu ((((sach v) OR (sach vay))) or (sach 2)) nang xa hoi. hieu va cam xuc van thanh vi su triet*.
