Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thuc dan » thuc hanh, hoc dan
hanh tai » thanh tai, hang tai, han tai
hanh vai » hanh vi, hanh va, hanh van
vu sach » vu bach, su sach, vu khach
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
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: vu sach ky dang xa hoi. hieu ve am ((thuc dan) or (thuc vat)) ((hanh vai) OR (hanh tai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky dang xa hoi. hieu ve am ((thuc dan) OR (thuc vat)) ((hanh vai) OR (hanh tai)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky dang xa hoi. hieu ve am ((thuc dan) or (thuc vat)) ((hanh vai) OR (hanh tai)) cua triet*".
