Perhaps you should try some spelling variations:
dinh dai » dinh dat, sinh dai, dinh dao
te sach » toc sach
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
ve chat » va chat, van chat
hieu ve » hieu va, hieu van
xuc va » duc va, tuc va, xac va
y nang » ky nang, ly nang, v nang
luc va » duc va, tuc va, loc va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang x hoi. hieu ve chat ((xuc va) or (luc va)) dinh dai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang x hoi. hieu ve chat ((xuc va) OR (luc va)) dinh dai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang x hoi. hieu ve chat ((xuc va) or (luc va)) dinh dai ((cua tre) OR (cuu tre))*".
