Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
va hanh » van hanh, va thanh, va danh
ve cham » va cham, ve chat, vu cham
tu sach » thu sach, te sach, tu cach
nang xa » nang x, lang xa, nang ma
su sach » so sach, vu sach
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua
ve cam » ve cac, va cam, ve cai

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

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