Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
va cham » va chat, va tham
thuc va » thuc vat, thuc dan, thuc day
va danh » va dinh, va dan, va hanh
danh di » danh du, xanh di, danh dien
ve cam » ve cham, ve cac, va cam
sac ky » cac ky, sai ky
te sac » te sach, te cac, te san
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang x hoi. hieu ((ve cam) or (va cham)) thuc va danh di ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang x hoi. hieu ((ve cam) OR (va cham)) thuc va danh di ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang x hoi. hieu ((ve cam) or (va cham)) thuc va danh di ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang x hoi. hieu ((ve cam) or (va cham)) thuc va danh di ((cua triet) OR (su triet))*.
