① A recent online post on Shenzhen's public restrooms by a woman surnamed Wang, who worked in Shenzhen and returned to her hometown for the Spring Festival holiday, has caused a discussion of what people miss the most about Shenzhen when they leave the city.

② Wang said on her WeChat that Shenzhen is a very convenient city, which is why she loves it.
③ "There is always toilet paper in the restrooms. But back in my hometown, you have to scan a QR code to pay for it, and unluckily, the app doesn't work sometimes."
④ On the internet, many travellers, including those visiting the city, shared good memories of Shenzhen's public restrooms. "Shenzhen's public restrooms are clean. They have clean air, hand soap, and hand dryers. Some are air-conditioned and even with showers. What is the most important is that they have toilet paper," said people praising the restrooms.
⑤ The praise is the result of the "toilet revolution", which started in 2017, asking the city's 4,500 public toilets to offer free toilet paper. To get all the restrooms to take part in the "revolution", the government introduced monthly public restroom grades based on the environment of public restrooms across the city.
⑥ The restroom services also include a family restroom, which is meant for families or anyone who needs more personal space or time because of a disability. The government says that one third of the city's public restrooms have a family restroom.
⑦ Meanwhile, LED boards placed at the doors of many new restrooms in shopping centres and at the airport show information about waiting times and the number of empty toilets, along with weather and air quality information. The government says the city will go on improving the service and smart features of public restrooms.
