In the video itself, posted on Chinese social media platform Sina Weibo, a range of shouts and noises can be heard from onlookers.
The powerful Long March 3B rocket, used to carry satellites to medium and geosynchronous Earth orbits, is almost 55 metres long, with a diameter of 3.35 metres on the core stage. The launcher has a mass at liftoff of 458,970 kg, or just over 1 million pounds.
The four 2.25 m diameter, 15 m long strap-on boosters are filled with unsymmetrical dimethylhydrazine (UDMH) and dinitrogen tetroxide (N2O4) hypergolic propellant, which is highly toxic.
The booster did not hit any people or buildings, but the still burning wreckage will have posed a serious health hazard to locals who approached to film the debris, as seen below.

The footage comes in stark contrast to United States launches, which send launch vehicles over the ocean, while private company SpaceX has mastered landing its Falcon 9 first stages back at launch sites and on drone ships off the coast.
China's first three launch sites were established during the Cold War, with Jiuquan and Taiyuan constructed deep inland for security reasons. These included tensions with the Soviet Union spilling over into border skirmishes and the United States considering preemptive strikes against China on sites linked to nuclear weapon launch capabilities.
This means that today's space launches pass over inhabited areas. Though drop zones for Long March rocket stages are carefully calculated and launch notices and procedures put in places, events like the above are all too common, especially with China's space activities expanding greatly in recent years.

The newest site, the Wenchang Satellite Launch Centre on Hainan island, is a coastal site, bringing launches into a more open age. However it is only used for the Long March 5 and 7 rockets, which have only just debuted in the last two years.
The China Great Wall Industry Corporation (CGWIC), a subsidiary of the main contractor for the Chinese space programme, CASC, said it plans to launch 14 Long March 3A, B and C variant rockets this year, including 8 launches for the Beidou system.

Most of the 8.5 tonne space lab will burn up on reentry, with remaining debris capable of landing anywhere within 43 degrees North and South.
CASC subsidiaries, the Shanghai Academy of Space Technology (SAST) and China Academy of Launch Vehicle Technology (CALT) are looking into reusability for its respective Long March rocket vehicles, while CASC itself has stated plans to make all its launch vehicles fully reusable, but not until around 2035.
