Perhaps you should try some spelling variations:
su triet » su viet, ve triet
thanh vi » hanh vi, thanh va, thanh ve
su tien » su kien, su hien, tu tieng
xuc gia » duc gia, luc gia, tuc gia
hieu ve » hieu va, hieu van
tang ma » tang van
hai ky » thai ky, hoi ky, hai ly
ve cam » ve cham, ve cac, va cam
su hai » su tai

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

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