Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hanh tai » thanh tai, han tai, hinh tai
hang tai » hang va
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach ky nang xa hoi. hieu va cam xuc va ((hanh tai) or (((hang tai) OR (dung tai)))) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky nang xa hoi. hieu va cam xuc va ((hanh tai) OR (((hang tai) OR (dung tai)))) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky nang xa hoi. hieu va cam xuc va ((hanh tai) or (((hang tai) OR (dung tai)))) cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach ky nang xa hoi. hieu va cam xuc va ((hanh tai) or (((hang tai) OR (dung tai)))) cua triet*.
