Well, for 2022 I found that the average wage is 2600¥ or 330€ per month (with enormous differencs between the regions). That means a flat is 4 annual salaries on average, assuming ithe 15000$ or 14000€. That’s not that much off a difference to Germany, where I am from.
So one could argue that this is just the advise “get a job and buy a house!!!” To a homeless person.
But keep in mind that here you compare a house (!) in the US, to a single bedroom apartment in china. That is quite a difference.
