Girls dressed in “Hanfu”, or Han clothing, prepare for an event to mark the traditional Qixi festival, the Chinese equivalent of Valentine's Day, at a park in Beijing, China, August 7, 2019. Chinese for “Han clothing”, “Hanfu” is based on the idea of donning costumes worn in bygone eras by China's dominant Han ethnicity. Some of the most popular styles are from the Ming, Song and Tang dynasties. Hanfu enthusiasts doubled to two million in 2018 from a year earlier, according to a survey by Hanfu Zixun, a popular community account on the Wechat social media platform.

Retirees gather in brokerage houses dotted around China also to enjoy some company and savour the air conditioning on hot days. Some start as young as 13, trading from home with an eye on future careers in finance. Winning isn't guaranteed. This year, among the most turbulent in China's financial history, its stock markets more than doubled in the six months to May, only to crash amid concerns that growth in the country, which makes everything from cars to steel, is slowing faster than previously thought.
