Perhaps you should try some spelling variations:
thien van » thi van
sach van » sach han, sach va, bach van
van hanh » van thanh, ban hanh, van anh
doi cua » dai cua, hoi cua
xuc van » duc van, luc van, vuc van
su sach » so sach, vu sach
nang xa » lang xa, nang ma, mang xa
cau xuc » cam xuc, cau luc, cau truc
van cau » van dau, van hau, van chat
di cua » dai cua, de cua, do cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach van ((nang xa) or (nang x)) hoi. thien van cau xuc van hanh ((di cua) OR (doi cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach van ((nang xa) OR (nang x)) hoi. thien van cau xuc van hanh ((di cua) OR (doi cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach van ((nang xa) or (nang x)) hoi. thien van cau xuc van hanh ((di cua) OR (doi cua)) triet*".
