Hello! The purchase restriction order issued by Xi' an has the following explanation for college students: the household registration of college students belongs to collective accounts, and they stay for a short time during school. When buying a house, you can't treat it as Xi 'an household registration, so you can't buy a house in Xi 'an city in their name. Only after graduating from college, with registered permanent residence in the urban area and a stable population in Xi 'an, are eligible to buy a house. If the parents of college students have plans to buy a house in Xi 'an, they need to provide their parents' tax payment certificate or social security payment certificate for more than one year. Secondly, zhouzhi county is a county under the jurisdiction of Xi 'an, so zhouzhi county's household registration is regarded as Xi 'an's household registration.
