The median income for office workers in Beijing is around 6,900 yuan, and this income already excludes the elderly and children. In other words, earning 7,000 yuan a month in Beijing means you are earning more than half of the workers here.

Looking at it this way, if you can earn 7,000 yuan in a small place, that's actually quite good, surpassing half of the people in first-tier cities.
But don't compare it to the upper limit in Beijing, which is astonishingly high; residents' savings amount to nearly 8 trillion yuan, and this is cash savings, not including real estate.
The per capita savings is 350k yuan (including the elderly and children), and the average household savings is a million.
Of course, in reality, many people don't have that much savings, so some people's savings are much higher than this.
So, the essence of happiness is not to compare with those who are too wealthy; you can't compete, and you truly can't compare. $ETH
