Perhaps you should try some spelling variations:

va thanh » gia thanh, ban thanh, va tinh
te sach » toc sach
cam luc » cau luc
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
ly nang » ky nang, ly hang, ly vang
y nang » ky nang, v nang, may nang
do cua » doi cua, co cua, de cua
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) OR (ly nang)) x hoi. hieu va ((cam luc) or (cam xuc)) va thanh do cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (ly nang)) x hoi. hieu va ((cam luc) OR (cam xuc)) va thanh do cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (ly nang)) x hoi. hieu va ((cam luc) or (cam xuc)) va thanh do cua tre*".
