Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thu nang » thu hang, thu bang, tho nang
va thanh » gia thanh, ban thanh, va tinh
thi nang » thi cong, ki nang, thi hanh
chat xuc » chat huu, cam xuc, chao xu
va hanh » van hanh, va danh, ban hanh
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
ve chat » va chat, van chat

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 ((thu nang) or (thi nang)) xa hoi. hieu ve chat xuc ((va hanh) OR (va thanh)) dai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((thu nang) OR (thi nang)) xa hoi. hieu ve chat xuc ((va hanh) OR (va thanh)) dai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((thu nang) or (thi nang)) xa hoi. hieu ve chat xuc ((va hanh) OR (va thanh)) dai cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((thu nang) or (thi nang)) xa hoi. hieu ve chat xuc ((va hanh) OR (va thanh)) dai cua triet*.
