Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vi » hanh vi, thanh va, thanh ve
thuc gia » thuc giai, thue gia, thuc dia
anh thuc » am thuc, dan thuc, anh tu
cuu tre » cua tre, cau tren, cau treo
so sanh » do sanh
ly nang » ky nang, ly hang, ly vang
hieu va » lieu va, hieu qua
va anh » van anh, va danh, va hanh
y nang » ky nang, v nang, may nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sanh ((y nang) OR (ly nang)) xa hoi. hieu va anh thuc gia thanh vi ((cuu tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sanh ((y nang) OR (ly nang)) xa hoi. hieu va anh thuc gia thanh vi ((cuu tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sanh ((y nang) OR (ly nang)) xa hoi. hieu va anh thuc gia thanh vi ((cuu tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: so sanh ((y nang) OR (ly nang)) xa hoi. hieu va anh thuc gia thanh vi ((cuu tre) or (cua triet))*.
