It is good to travel to Ningwu and buy some local specialties for friends and relatives, such as Cheng Niyan, Ningwu Yingpan Mushroom, Ningwu reed mat, a nest of silk, apricot petals and so on. Among them, "Wosi", also known as "pancake", is a specialty of ningwu county, Xinzhou, Shanxi, with a long history, and was once the dessert of senior banquets. "A nest of silk" is crisp, crisp and fragrant, with the characteristics of yellow color, sweet taste and crisp quality. Sweet and delicious when eaten fresh, crisp and delicious when eaten dry. It looks like a dragon curled up and waiting to soar, holding a thread, putting a nest of silk, moving and breaking a pile; Chew, it's delicious. Store for one to two months, the color and taste remain unchanged, and the hardness remains unchanged. Later, with the people's increasingly affluent life, there was no shortage of white flour and sesame oil, and "a nest of silk" flourished in the rural areas of the county and became a good product for people to welcome guests. There is also Cheng Ni inkstone, one of the four famous inkstones in China, which is made of special cement. Because of the different firing process and time, it can be in a variety of colors, some of which are multicolor, with special attention to carving technology, such as relief, semi-tire, three-dimensional and transparent. The shapes of inkstone are round, oval, semicircle, square, rectangle and any shape.

Landscape figures, flowers and trees, birds and animals are carved on the plane; There are rhinoceros looking at the moon, White Pagoda of Mount Tai, the Goddess Chang'e flying to the moon and so on. These carved inkstones are concise, ingenious, vivid, vivid and interesting. The desk placed in front of the desk is not only one of the four practical treasures of the study, but also an ornamental art treasure, which Chinese and foreign tourists buy as souvenirs.
