If A owns a piece of land that has been passed down from generation to generation, and its market price is 100,000 yuan  But if A's subjective evaluation is higher than the market price, assuming 150,000 yuan, according to the property rules, A is expected to receive 150,000 yuan; but if the land is expropriated, he can only be compensated by the market price
If the expropriated land is used for public purposes, this balance will be converted into public welfare; if the expropriated land is used for commercial development, this balance will come into the developer's private wallet
The government expropriates one person's property and then transfers it to another person or unit, which does not belong to private use of public power.
