A total of 2,021 unmanned aerial vehicles (UAVs) put on a dazzling show over Guangzhou's Huangpu district on June 27 to celebrate the 100 anniversary of the founding of the Communist Party of China.

The UAV show was staged by local tech company Ehang at Guangzhou Science City, China-Singapore Guangzhou Knowledge City, and Huangpu Port.

The UAVs form the shape of the Party emblem and Chinese characters that read "Always Follow the Footsteps of the CPC".

The UAVs show the pattern of a red boat, where the CPC's first National Congress was held in 1921.

The sky is lit up by the official event logo to mark the 100th anniversary of the founding of the CPC.

Locals take photos of the CSGKC logo, formed by UAVs over Fenghuang Lake.

The UAVs create the pattern of a Huangpu landmark - the Gate of Science.

UAVs write the Chinese characters "Huangpu Iron Army: Everyone Matters".
