Perhaps you should try some spelling variations:
thanh xuc » thanh xuan, thanh huy, hanh xu
van thanh » ban thanh, van tuan
cua triet » cua viet, su triet, va triet
hieu van » hieu va, thien van, lieu va
te sach » toc sach
ty nang » ty xang, ty hang, ly nang
va danh » va dinh, va dan, va hanh
danh di » danh du, xanh di, danh dien
cua tre » cua te, cuu tre, dua tren
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: te sach ((ty nang) or (ky nang)) xa hoi. hieu van thanh xuc va danh di ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ty nang) OR (ky nang)) xa hoi. hieu van thanh xuc va danh di ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ty nang) or (ky nang)) xa hoi. hieu van thanh xuc va danh di ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ((ty nang) or (ky nang)) xa hoi. hieu van thanh xuc va danh di ((cua tre) OR (cua triet))*.
