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.
