Accidentally drew two top floors. Can I ask to change them?

Of course. Because property rights exchange is the right of the relocated households, if they are not satisfied with the floor of the resettlement house, they can be exchanged. Legal basis: Article 5 of the Civil Law of People's Republic of China (PRC) stipulates that civil subjects should follow the principle of voluntariness and establish, change and terminate civil legal relations according to their own wishes.
