Walking through Singapore in March 2022

On the way back from Sydney to Germany I had a stay of 9 hours in Singapore. I decided logically to visit the city. Several days before I had to fight with a variety of forms and regulations, because they kept changing due to the crisis and everything was not so clear. Finally, when entering the country, no one asked for anything other than the passport and I was in the country within 30 min after landing. There I took the train east and then walked through the city through some tropical parks to the beach and back.
