Three red helicopters adorned with the Chengdu 2021 mascot and logo visited the Sports Park construction site, with Rongbao emerging from one to greet the workers. 

He gave the workers a bag of gifts each, including the newly launched Chengdu 2021 themed scratch lottery tickets.

There are six types of lottery ticket, with each one showing off Chengdu's expertise in either culture, tourism, sports, food, music or exhibitions. 

A maximum of 100,000 Chinese Yuan (£11,000/$14,000/€13,000) can be won.

"Thank Rongbao for bringing us good luck!", said a worker who won 20 Chinese Yuan (£2/$3/€3).

"I hope everyone can enjoy this happiness during the World University Games".

Rongbao's visit fell during Chinese New Year celebrations, with workers staying on site to ensure the construction work is ready on time. 

The Dong'an Lake Sports Park is expected to be one of the main sites for Chengdu 2021, with the Opening and Closing Ceremonies set to take place at the Dong'an Lake Sports Center Gymnasium.

The complex is spread out over 678 acres and will also consist of four other multi-functional venues with around 18,000 spectator seats each.

Chengdu 2021 is scheduled for August 8 to 19, with a total of 18 sports set to feature on the programme.
