Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc dan » thuc hanh
hanh vai » hanh vi, hanh va, hanh tai
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu ve » hieu va, hieu van
vai cua » dai cua, hai cua, lai cua
ve am » va am

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 ky lang xa hoi. hieu ve am ((((thuc dan) OR (hoc dan))) or (thuc vat)) hanh vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky lang xa hoi. hieu ve am ((((thuc dan) OR (hoc dan))) OR (thuc vat)) hanh vai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky lang xa hoi. hieu ve am ((((thuc dan) OR (hoc dan))) or (thuc vat)) hanh vai cua triet*".
