Perhaps you should try some spelling variations:
ha triet » nha triet, va triet, hanh triet
hanh lam » thanh lap, hanh kem, hanh va
va hanh » van hanh, va thanh, va danh
tu sach » thu sach, su sach, te sach
y nang » ky nang, ly nang, v nang
ve cac » va cac, vien cac
ve cam » ve cham, va cam, ve cau
xuc va » duc va, tuc va, luc va
lam ha » nam ha, dam ha, lam chat
ve cai » va cai, ve tai, ve cau
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 sach y nang x hoi. hieu ((((ve cam) OR (ve cai))) or (ve cac)) xuc va hanh lam ha triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang x hoi. hieu ((((ve cam) OR (ve cai))) OR (ve cac)) xuc va hanh lam ha triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang x hoi. hieu ((((ve cam) OR (ve cai))) or (ve cac)) xuc va hanh lam ha triet".
• Adding a wildcard symbol may retrieve word variants: tu sach y nang x hoi. hieu ((((ve cam) OR (ve cai))) or (ve cac)) xuc va hanh lam ha triet*.
