I was very happy when I first got the genuine authorization of China Film last year. However, this project is the most challenging product I have ever done so far (I made the details of the product from scratch and the shooting details page in the later period). At present, it is strictly selected and put on the shelves in Netease. No matter how hard the sales volume is, it is still affirmed by others. At the beginning, the company gave me the target: to develop a new product with IP of wandering earth around the starting point of selling stones and popularizing science stones, and to have a complete playing method. I selected twelve gems of color and texture from the supplier to match the twelve constellations to create gameplay, and the connection of the twelve constellations was also redesigned by me based on the prototype. The existence of photo frames is because after selling gems to children, they mainly play a role in popular science and at the same time have collection value. The play of constellation photo frames can enable children to recognize or deepen the value of this product for a long time.
