Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va thanh » gia thanh, ban thanh, va tinh
cua tre » cua te, cuu tre, dua tren
soc ban » hoc ban, coc ban, soc ba
hieu va » lieu va, hieu qua
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
san ky » sang ky, van ky, dan ky
so ban » sao ban, so bang, co ban
te san » te ban, ke san, tu san

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: te san ky dang xa hoi. hieu va thanh ((soc ban) OR (so ban)) hanh vi ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te san ky dang xa hoi. hieu va thanh ((soc ban) OR (so ban)) hanh vi ((cua tre) or (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: te san ky dang xa hoi. hieu va thanh ((soc ban) OR (so ban)) hanh vi ((cua tre) or (cua triet))*.
