Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh vai » hanh vi, hanh va, hanh van
hanh tai » thanh tai, hang tai, han tai
so sach » so sanh, bo sach, co sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam duc » cam xuc, cao duc, pham duc
y nang » ky nang, ly nang, v 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 sach y nang xa hoi. ((hieu ve) or (hieu qua)) cam duc va ((hanh vai) OR (hanh tai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y nang xa hoi. ((hieu ve) OR (hieu qua)) cam duc va ((hanh vai) OR (hanh tai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang xa hoi. ((hieu ve) or (hieu qua)) cam duc va ((hanh vai) OR (hanh tai)) cua triet".
• Adding a wildcard symbol may retrieve word variants: so sach y nang xa hoi. ((hieu ve) or (hieu qua)) cam duc va ((hanh vai) OR (hanh tai)) cua triet*.
