Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
sach ly » sach y, sach lo, sach ty
ly nang » ky nang, ly hang, ly vang
cua tre » cua te, cuu tre, cua triet
xac va » tac va, bac va, mac va
tuc va » thuc va, truc va, tuc xa
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, x ho
ac va » tac va, bac va, mac va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly nang x hoi. lieu va cac ((((xac va) OR (ac va))) or (tuc va)) hanh vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly nang x hoi. lieu va cac ((((xac va) OR (ac va))) OR (tuc va)) hanh vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly nang x hoi. lieu va cac ((((xac va) OR (ac va))) or (tuc va)) hanh vi cua tre*".
