The country's box office also raked in 55.9 billion yuan, growing more than 22 times compared to that of 1991.

On top of plenty of goods and services stimulating consumption, rising income also boosted the consumption momentum. According to the National Bureau of Statistics, in 2017 per capita disposable income of residents came in at 25,974 yuan, up 22.8 times that of 1978.

China's economy expanded at an average rate of 9.5 percent over the last 40 years, far beyond the world economy's 2.9 percent in the same period. And its GDP rose from 367.9 billion yuan in 1978 to 82.71 trillion yuan in 2017.

The country's industrial structure has continued to optimize and its economic growth has been driven by consumption, investment and export. At the same time, China has recorded the largest foreign reserve in the world.
