Which Chinese stock index fell sharply during the 2015 Chinese stock-market crash?

The Shanghai Composite fell sharply during the 2015 Chinese stock-market crash.

The index tracks all A-shares and B-shares listed on the Shanghai Stock Exchange. Chinese equities had risen rapidly in the first half of 2015, encouraged by retail investor participation, margin borrowing, and expectations of continued economic support.

The Shanghai Composite reached a 2015 closing high of 5,178.19 on June 12. It then dropped steeply, with several volatile sessions and government measures intended to stabilize trading. The turbulence spread to other markets and contributed to a worldwide period of concern about China’s economy and commodity demand.

The Shenzhen Component was also heavily affected, and Hong Kong’s Hang Seng Index declined as well. The Shanghai Composite is the most specific answer for the widely reported mainland Chinese benchmark at the center of the episode.
