There will be an emergency contact button or calling device in the subway car or platform, which can be used to report to the staff. You can also directly ask the subway staff around you for help. They will provide help and guide you to the corresponding cleaning staff. Timely reporting can help the subway company to take measures quickly to maintain the sanitation of the subway environment and the comfortable experience of passengers.
