The visit to Heilongjiang Science and Technology Museum is well prepared because of its extraordinary shape. When you enter, you will find surprises everywhere. First of all, there are many escalators in the library, whose steps are not uniform, and the two colors of green, black, green and black appear alternately, which is an extraordinary idea. Secondly, there are three-dimensional drawings, visiting many science and technology museums at home and abroad, the first time I saw this design. The design is close to children's psychology and can stimulate creativity. Frogs and bees have a large number of living objects. It's definitely a worthwhile trip.
