More families were also found taking in sights of nature as March is usually when spring flowers such as cherry trees, tulips and Yulan magnolias, the city's symbolic flower, blossom.

"We can see tulips and purple-leafed plum in full bloom. Spring has arrived," says Liang Hong, who went to the Jing'an Sculpture Park on Sunday with her husband and her mother.

Every visitor was wearing a mask and had their temperature taken at the entrance, says Liang, who took her first trip to the park in nearly two months.

Besides ensuring that all visitors wear masks, public venues have also introduced limits to visitor numbers, encouraged people to stay at least a meter apart and conducted temperature checks at the entrances.

According to the city's plan, apart from the 17 parks that are currently undergoing renovation or maintenance, the rest of its 335 parks will be opened to the public by Friday.

Other venues that have reopened are popular tourist attractions such as Disneytown, Madame Tussaud's and Shanghai Tower, China's highest building, which sits in the heart of Lujiazui, the city's financial district.
