Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hanh hai » thanh hai, nhanh hai, hang hai
van hanh » van thanh, ban hanh, van anh
duc van » duc va, duc tan, duc manh
sach tu » sach thu, cach tu, sach ty
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ve pham » vi pham, v pham, ve phan

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach tu) or (sach y)) nang xa hoi. hieu ve pham duc van hanh hai ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tu) OR (sach y)) nang xa hoi. hieu ve pham duc van hanh hai ((cua triet) OR (su triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tu) or (sach y)) nang xa hoi. hieu ve pham duc van hanh hai ((cua triet) OR (su triet))*".
