Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
cham xuc » cam xuc, chat xuc, cham soc
sach han » sach tham, sach danh, sach nang
ban hanh » ban hang
sach van » sach va, bach van, cach van
van anh » van thanh, tuan anh, van minh
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ve cham » va cham, ve chat, vu cham
ki su » ky 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: te ((sach van) OR (sach han)) nang xa hoi. hieu ve cham xuc ((van anh) OR (ban hanh)) ki su triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach van) OR (sach han)) nang xa hoi. hieu ve cham xuc ((van anh) or (ban hanh)) ki su triet~".
• Adding a wildcard symbol may retrieve word variants: te ((sach van) OR (sach han)) nang xa hoi. hieu ve cham xuc ((van anh) or (ban hanh)) ki su triet*.
