Hangzhou 2022 organizers unveiled the torch for the event, titled "Eternal Flame," on Saturday, which marks the one-year countdown to the opening ceremony.

Inspired by the Liangzhu Culture, the torch symbolizes the inheritance of Chinese culture through generations spanning 5,000 years.

The ruins of the ancient capital of Liangzhu, which is now located in Hangzhou, the eastern province of Zhejiang, were included on the UNESCO World Heritage List in 2019.

The torch is 73 centimeters in length and weighs 1.2 kilograms. The design is based on the evolution of fingerprint patterns related to the Liangzhu Culture. 

Its base is embossed with eight water veins symbolizing the evolution of civilization and representing the eight major river systems in Zhejiang Province. The top is characterized by the meaning of Jade Cong to show harmonious square-round integration. And the burner nozzle is designed from the earliest oracle bone inscription of Jade Cong with the implied meaning of "light traveling in cycle inside."

The design intended to highlight the uninterrupted continuity of Chinese civilization.

The raw materials of the torch were digitally mapped to the blockchain and the traceability mechanism is used to ensure authenticity. The grip is made of recycled, eco-friendly raw materials and the fuel is biomass gas, which is clean, safe and reliable.
