Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
bach dang » bach dan, bach khang, cach mang
ve triet » va trien
su triet » su viet, su tien
thanh vi » hanh vi, thanh va, thanh ve
bach van » bach dan, cach van, bach xuan
xuc van » duc van, luc van, vuc van
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ve cam » ve cham, ve cac, va cam

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((bach van) or (bach dang)) nang xa hoi. hieu ve cam xuc van thanh vi ((su triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((bach van) OR (bach dang)) nang xa hoi. hieu ve cam xuc van thanh vi ((su triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((bach van) or (bach dang)) nang xa hoi. hieu ve cam xuc van thanh vi ((su triet) OR (ve triet))".
• Adding a wildcard symbol may retrieve word variants: tu ((bach van) or (bach dang)) nang xa hoi. hieu ve cam xuc van thanh vi ((su triet) OR (ve triet))*.
