On Friday night, a 3D light show in downtown Chongqing impressed audience at the launching ceremony of 2020 Chongqing Nightlife Festival as the city continues to drive economic growth.

The show staged at the city landmark Chongqing Liberation Monument featuring a theme of a city's that never sleeps and a cyberpunk's technopolis.

During the festival, more than 150 activities will be held throughout the city until October, including a light show on the banks of the Yangtze and Jialing rivers every night.

Due to the heat and humidity, Chongqing is called one of the "three furnaces" of China, along with Nanjing in Jiangsu province and Wuhan in Hubei province.

According to the government statistics, 60 percent of the consumption in Chongqing happens at night in recent years.

Since last year, authorities nationwide have beefed up measures to develop the nighttime economy, with steps to encourage post-dusk business activities and later closing hours at museums and art galleries.

In July, Chongqing issued an action plan to bolster nighttime economy and consumption in the following five years. By 2025, Chongqing is expected to build a core zone and 10 high-quality demonstration areas for the nighttime economy across the city.

Nighttime economy refers to business activities between 6 pm and 6 am in the service sector.

As part of the festival, 2020 China Nighttime Economy Development Summit was held on Saturday in Chongqing.
