Perhaps you should try some spelling variations:
va truyen » hoa truyen, co truyen, di truyen
va trien » va thiet, va tuyen, va tieng
hanh vai » hanh vi, hanh va, hanh tai
va hanh » van hanh, va thanh, va danh
su sach » so sach, vu sach
cam tuc » cam tu, nam thuc, dam thuc
hieu va » lieu va, hieu qua
nang ma » tang ma, sang ma, nang cao
y nang » ky nang, ly nang, v nang
ma hoi » mai hoi, xa hoi, ma hoa

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang ma hoi. hieu va ((cam tuc) or (cam xuc)) va hanh vai ((va trien) OR (va truyen))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang ma hoi. hieu va ((cam tuc) OR (cam xuc)) va hanh vai ((va trien) OR (va truyen))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ma hoi. hieu va ((cam tuc) or (cam xuc)) va hanh vai ((va trien) OR (va truyen))*".
