In solemn observance of International Museum Day, scores of Shanghai museums are waiving the entry fee to their wondrous and edifying exhibitions. 105 museums in total are free entry, with the majority of that number maintaining that offer into the weekend. The city's heavy hitters, the Shanghai Science and Technology Museum and the Shanghai Natural History Museum are offering half price admission for that periods. The museum celebration bender goes on into next Friday when 46 museums will extend their admission hours to 9pm and "hold colorful events for the public in the evening." At the Shanghai Museum of TCM, for example, "visitors can learn how to roll dried mugwort into sticks for moxibustion." Party!
