This nitro is not a whistle, I never knew what the nitro was, and I once read it as shaozi, in fact, people are called xiaozi, that is, glass. From the section of the Xiaoyu Canal to the pedestrian street, there are full of nitro restaurants, of which the advertisements and stores in the north are the most popular. There are a variety of glass products, there are tableware and oil pots, and there are crafts, which are extremely exquisite. The people of Xiaoyu really made the glass a realm!
