Perhaps you should try some spelling variations:
te sach » toc sach
hieu ve » hieu va, hieu van
lua tre » cua tre, luy tre, dua tren
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
dao vi » dao voi, dao ve, dao va
vi lua » vi luu
x hoi » xa hoi, o hoi, x ho

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: "te sach y nang x hoi. hieu ve cac ((xuc va) OR (tuc va)) dao vi lua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang x hoi. hieu ve cac ((xuc va) OR (tuc va)) dao vi lua tre*.
