Legal analysis: Expropriation within the red line: According to the provisions of relevant laws in China, the expropriation department will draw up an expropriation compensation plan when the house is demolished, which includes the scope of expropriation. The parties can check the expropriation compensation plan to determine whether it is within the red line.

1. The house expropriation department draws up the expropriation compensation scheme and reports it to the people's government at the city or county level. The people's governments at the city and county levels shall organize relevant departments to demonstrate and publish the compensation scheme for expropriation and solicit public opinions. The period for soliciting opinions shall not be less than 3 days.

2. The people's governments at the municipal and county levels shall promptly announce the situation of soliciting opinions and making amendments according to public opinions. Because the old city reconstruction needs to expropriate houses, and most expropriated people think that the expropriation compensation scheme does not conform to the provisions of these regulations, the people's governments at the city and county levels shall organize a hearing attended by expropriated people and public representatives, and modify the scheme according to the hearing.

3. The house expropriation department shall organize investigation and registration on the ownership, location, use and construction area of houses within the scope of house expropriation, and the expropriated person shall cooperate. The survey results shall be announced to the expropriated person within the scope of house expropriation.
