Perhaps you should try some spelling variations:
vat dung » van dung, va dung, viet dung
ky dang » ky nang, ky danh
dang xa » dang xay, lang xa, dang ha
cua tre » cuu tre, cua triet, dua tren
so sac » so sach, so dac
tu vat » tu va, tu van, tu bat
cua te » cua tu
va tam » van tam, va tham, va tac
sac ky » cac ky, sai ky
ve tam » ve tac, ve tai, se tam

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

• If you are trying to use Boolean operators, they must be ALL CAPS: so sac ky dang xa hoi. hieu ((ve tam) OR (va tam)) tu vat dung cho ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sac ky dang xa hoi. hieu ((ve tam) OR (va tam)) tu vat dung cho ((cua tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: so sac ky dang xa hoi. hieu ((ve tam) OR (va tam)) tu vat dung cho ((cua tre) or (cua te))*.
