Perhaps you should try some spelling variations:
hanh than » hanh han, hanh nhan, hanh phan
thien van » thi van
cua triet » cua viet, su triet, va triet
than cua » nhan cua, thai cua, ban cua
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
van bac » van ban, van bao, van hac
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang x ho. thien van bac ((xuc va) OR (tuc va)) hanh than cua triet~".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang x ho. thien van bac ((xuc va) OR (tuc va)) hanh than cua triet*.
