Where to consult information when buying a house in Xi 'an?

Should I withdraw the provident fund or borrow money to buy a house in Xi 'an? If it is withdrawn, there will be no problem. If it is a loan, it depends on whether Xi 'an supports Chengdu Provident Fund. As far as I know, the provident fund is managed locally. Maybe Xi doesn't support provident fund loans. You need to consult Xi 'an.
