Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
vanh tai » van tai, hanh tai, anh tai
chat xuc » chat huu, cam xuc, chao xu
cham xuc » cam xuc, cham soc, pham duc
tai cua » thai cua, tai cuc, tri cua
va vanh » va van, va danh, va hanh
tu sach » thu sach, te sach, tu cach
hieu va » lieu va, hieu qua
su sach » so sach, vu sach
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) OR (su sach)) ky nang o hoi. hieu va ((cham xuc) OR (chat xuc)) va vanh tai cua triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ky nang o hoi. hieu va ((cham xuc) OR (chat xuc)) va vanh tai cua triet~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) ky nang o hoi. hieu va ((cham xuc) OR (chat xuc)) va vanh tai cua triet*.
