China's changes through reform on documentary

Between the 1980s and early '90s, many residents of Shanghai lived in small homes, with members of some families all eating and sleeping in rooms less than 10 square meters each.

In a span of five years, photographer Zhou Ming visited more than 1,000 such families, capturing both their predicament and desire to strive for a bit more comfort.

Zhou's footprints are shown in a 20-episode documentary series, titled Witness the Changing China 1949-2019, which was recently released on Chinese streaming platform Youku.
