Here, we present some of the most striking images around the world this past weekChildren cool off themselves at a wading pool in Toronto, Canada, on Sept 24, 2017
The vice-premier said China is willing to work with the US to prepare for President Trump's visit to China to ensure it is a great successVisiting Vice-Premier Liu Yandong, right, speaks with Jared Kushner, senior White House adviser, center, and Ivanka Trump, left, daughter of US President Donald Trump also serving as an adviser, in Washington DC, on Sept 27, 2017
Liu addressed a reception celebrating the 68th anniversary of the founding of the People's Republic of China at the Chinese embassy on WednesdayThe training course on the Chinese lion dance is part of the 2017 China Africa Cultures in Focus, an activity held by the Bureau for External Cultural Relations of Chinese Ministry of Culture to strengthen the cultural communication between China and African countriesThey kept practicing from morning until night, trying to master the basic skills of lion dance, routines and instrumental music within a short periodThe cultural center of the Jinpu New Area also arranged some courses for them to know about other traditional Chinese culture such as Chinese calligraphy, seal cutting, folk dance, paper-cutting, and pottery
The cultural center of the Jinpu New Area has undertaken the course for three consecutive years since 2015During the 35-day training course, they learned from Li Mingxu, the fifth generation successor of the Jinzhou Lion Dance, a provincial intangible cultural heritage that has been passed from generation to generation for more than a century
Ten students from Nigeria and Zambia learned how to perform Chinese lion dance at the Jinpu New Area in Dalian, Northeast China's Liaoning provinceThese changes may look pleasant, but not quite so to Derek Hyra, an associate professor at the American University School of Public Affairs and an expert on neighborhood change
Chen Weihua/China DailyHaving lived in Washington DC for almost five years, I have seen the city growing, with new construction and renovation projects happening in many streets and neighborhoodsHyra described how the "dark ghetto" has been turned into a "gilded ghetto"
To Hyra, it has caused not just residential displacement for African Americans but also political and cultural displacementHis book this year, Race, Class, and Politics in the Cappuccino City, is the result of his many years of field research on the issuesWhites are the majority now, accounting for 55 percent of the communityThe 14th Street near U Street, a traditional African American neighborhood, is now lined up with hip restaurants and bars in this photo taken on Sunday
The area, a 90 percent black neighborhood just a few decades ago, was only 30 percent African American by 2010Hyra described the massive transformation in the U Street/Shaw area, where the city's once most infamous open-air drug market has become a farmers' market now selling grass-fed beef and homemade duck egg ravioli
The Wharf residential and business project I visited recently is probably one of the biggestThe same urban renewal is happening in other parts of Washington
The U Street/Shaw and 14th Street area has fast been turned into an upscale neighborhood in recent years, with many new restaurants and shops opening and new apartment constructionOnly a short walk from the National Mall, it looks like a good place to live, work and hang out
