Can Gansu Changqing Oilfield Social Security buy a house in Xi 'an?

I can't. According to official website of Xi Housing and Construction Bureau, as of July 7, 2023, the policy of buying a house in Xi 'an is that social security must be paid in Xi 'an, and the foreign household registration has been paying social security or personal income tax in this city for six months or paying social security or individual income tax for two years or more before the date of buying a house, so the social security of Changqing Oilfield cannot buy a house in Xi 'an, Gansu.
