Perhaps you should try some spelling variations:
thien van » thi van
chat xuc » chat huu, chao xu, chat cua
van hanh » van thanh, ban hanh, van anh
hanh lam » thanh lap, hanh kem, hanh va
va triet » va thiet, va trien, ve triet
so sach » so sanh, bo sach, co sach
ty nang » ty xang, ty hang, ly nang
lam va » nam va, dam va, lam ha
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: so sach ((ty nang) OR (ky nang)) x hoi. thien van ((chat xuc) or (cam xuc)) van hanh lam va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ((ty nang) OR (ky nang)) x hoi. thien van ((chat xuc) OR (cam xuc)) van hanh lam va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ((ty nang) OR (ky nang)) x hoi. thien van ((chat xuc) or (cam xuc)) van hanh lam va triet".
• Adding a wildcard symbol may retrieve word variants: so sach ((ty nang) OR (ky nang)) x hoi. thien van ((chat xuc) or (cam xuc)) van hanh lam va triet*.
