Perhaps you should try some spelling variations:
pham chuc » pham duc, pham huu, kham chua
su triet » su viet, su tien
hanh hai » thanh hai, nhanh hai, hang hai
toc sach » hoc sach, doc sach, thuoc sach
ve triet » va trien
hieu vi » hieu voi, hieu va, hieu ve
sach ty » sach y, sach tu, sach thu
chuc va » thuc va, thuc vat
va hanh » van hanh, va thanh, va danh
ty nang » ky nang, ty xang, ty hang
ma hoi » mai hoi, ma hoa, me hoi

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

• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ty nang ((ma hoi) OR (xa hoi)). hieu vi pham chuc va hanh hai ((su triet) OR (ve triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ty nang ((ma hoi) or (xa hoi)). hieu vi pham chuc va hanh hai ((su triet) OR (ve triet))~".
• Adding a wildcard symbol may retrieve word variants: toc sach ty nang ((ma hoi) or (xa hoi)). hieu vi pham chuc va hanh hai ((su triet) OR (ve triet))*.
