Perhaps you should try some spelling variations:
ve triet » va trien
su triet » su viet, su tien
hanh hai » thanh hai, nhanh hai, hang hai
thuc dan » thuc hanh, hoc dan
su sach » so sach, vu sach
sach ky » sac ky, sach y, sach ty
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ve nam » he nam, va nam, le nam

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