The visa to Spain was refused. I want to appeal and ask for help.

The visa officer of the embassy has no reason to refuse the visa. It's no use complaining. The more deposit balance, the better. The more you provide, the better the visa. No one can guarantee that 100% will be sent. Reason for refusal: 1. Your exit record. If you have a lot of deposits but no exit record, you can't prove that you have money. You are very rich. Why didn't you travel abroad? 2. How many square meters is the real estate in Shanghai? If the quotation is too small, it is not enough to prove that you have money. Because the embassy first judges that the visa sender is a person who wants to immigrate illegally, and then excludes the possibility of your immigration by exclusion, that is, by having assets in China or other things you don't want to give up. So the richer the visa information, the better. It is useless to appeal, so you can only reapply, but if there is a qualitative change compared with the first application, it is beneficial to reapply.
