Perhaps you should try some spelling variations:
thien van » thi van
su triet » su viet, su tien, ve triet
sach van » sach han, sach va, bach van
hanh de » hanh ve, hanh kem
vuc van » duc van, luc van, thuc van
xuc van » duc van, luc van, xuc ban
su sach » so sach, vu sach
nang xa » lang xa, nang ma, mang xa
van cau » van dau, van hau, van chat
de su » den su, ve su, de tu

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) OR (vuc van)) hanh de su 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) OR (vuc van)) hanh de su 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) OR (vuc van)) hanh de su triet*".
