Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
van thanh » ban thanh, van tuan
su triet » su viet, su tien, ve triet
van hanh » ban hanh, van anh, van ban
hieu van » hieu va, thien van, lieu va
van cac » van hac, van cau, van bac
cac duy » cac du, cac quy, cach dua
sai ky » sac ky
su sai » su tai, su hai, su dai
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: su sai ky nang x hoi. hieu van cac duy ((van hanh) OR (van thanh)) vi ((cua triet) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky nang x hoi. hieu van cac duy ((van hanh) OR (van thanh)) vi ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky nang x hoi. hieu van cac duy ((van hanh) OR (van thanh)) vi ((cua triet) or (su triet))*".
