The Qing-Feng Steamed Dumpling Shop restaurant chain was listed by some travel agencies as a top tourist spot over the Spring Festival holiday, more than one month after President Xi Jinping visited an outlet on Dec 28. The restaurant near the Temple of the Moon in Xicheng district saw a huge boost in customers over the holiday period from Jan 31 to Feb 6, reporting that its business volume was 4.7 percent higher than the same period last year.
