You can't. According to the provisions of Article 28 of the Fire Protection Law, no unit or individual may damage, misappropriate or dismantle or stop fire control facilities and equipment without authorization, bury, occupy or block fire hydrants or occupy fire prevention spaces, occupy, block or close evacuation passages, fire exits and fire truck passages. The fire corridor is the second passage for evacuation. In case of fire or emergency, it shall not be closed or blocked. If it is closed, there is no way to escape in time in case of fire.
