Perhaps you should try some spelling variations:
dan thai » dang thai, dan thi, dan than
thai cua » than cua, tai cuc, tri cua
ky lang » ky nang, ky tang, tay lang
ky dang » ky nang, ky danh
cac xuc » cac nuoc, chat xuc, cac cuoc
cua tre » cua te, cuu tre, cua triet
tu san » thu san, tu ban, tu can
va dan » ca dan, va dao, va dau

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: tu san ((ky lang) OR (ky dang)) xa hoi. lieu va ((cac xuc) OR (cam xuc)) va dan thai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ((ky lang) OR (ky dang)) xa hoi. lieu va ((cac xuc) or (cam xuc)) va dan thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu san ((ky lang) OR (ky dang)) xa hoi. lieu va ((cac xuc) or (cam xuc)) va dan thai cua tre*.
