Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
cham xuc » cam xuc, cham soc, pham duc
chat xuc » chat huu, cam xuc, chao xu
vanh dai » van dai, vanh tai, lanh dao
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
va vanh » va van, va danh, va hanh
cua tre » cua te, cuu tre, dua tren
nang o » nang co, nang ho, nang ro
o hoi » co hoi, o hoc, o hai

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 sach ky nang o hoi. lieu va ((cham xuc) OR (chat xuc)) va vanh dai ((cua tre) OR (cua triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang o hoi. lieu va ((cham xuc) or (chat xuc)) va vanh dai ((cua tre) OR (cua triet))~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang o hoi. lieu va ((cham xuc) or (chat xuc)) va vanh dai ((cua tre) OR (cua triet))*.
