Actually, it's not very legal. If it is really legal, why not publish and implement it in the form of national laws or administrative regulations? Concealing the itinerary causes the epidemic to spread, which brings serious security risks and consequences to the country and society. I must have broken the law and should be punished according to law, but what is the causal relationship with my immediate and collateral relatives? If you live together, you can also think that you are not reporting or hiding. If you live independently, such as one in Beijing and one in Guangzhou, there is no difference between implementing this policy and a person committing a crime in feudal society. Therefore, the epidemic prevention policy should be treated differently, and it must not be across the board.
