Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
cua triet » cua viet, su triet, va triet
phat xuc » chat xuc, phat xuat, phap xu
va thanh » gia thanh, ban thanh, va tinh
thanh di » thanh doi, thanh de, thanh do
tu cach » tu cac
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, dua tren
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((tu cach) or (thuat sach)) ky nang x hoi. hieu va phat xuc va thanh di ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cach) OR (thuat sach)) ky nang x hoi. hieu va phat xuc va thanh di ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cach) or (thuat sach)) ky nang x hoi. hieu va phat xuc va thanh di ((cua tre) OR (cua triet))*".
