In this March 31, 2019 photo, an Egyptian student borrows a Bedouin wedding dress to pose for a photograph with Bedouin men from the Hamada tribe, in Wadi Sahw, Abu Zenima, in South Sinai, Egypt. Four Bedouin women are for the first time leading tours in Egypt’s Sinai Peninsula, breaking new ground in their deeply conservative community, where women almost never work outside the home or interact with outsiders. The tourists can only be women, and the tours can’t go overnight. Each day before the sun sets, the group returns to the Hamada’s home village in Wadi Sahu, a narrow desert valley.

Yan Mengjie sits on a boat as she poses for photos near Erhai Lake in Dali Bai Autonomous Prefecture, Yunnan province, China on June 16, 2019. Erhai is one of China's biggest freshwater lakes and a backdrop to the city of Dali, which drew 47 million visitors last year, more than triple the number in 2010. Hotels and homestays have sprung up along a 31-mile (50-km) stretch of lakeside road to accommodate tourists. But officials ordered some hotels demolished after President Xi Jinping during a 2015 visit called for the lake to be protected. (Photo by Tingshu Wang/Reuters)

In this July 8, 2019, photo, a monkey pulls on the clothes of Saraswati Dangol as she arrives to feed monkeys in the forest near Pashupatinath temple in Kathmandu, Nepal. For the past four years, Dangol has been bringing the bread every day to feed the monkeys. As soon as they see her with her white sack, they gather around her, some patiently waiting for their turn while others less patiently snatching the bread from her hands. Many of Dangol's regulars are elderly, or are mother or baby monkeys who are unable to fight for their share of food in the wild. (Photo by Niranjan Shrestha/AP Photo)

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.
