Universities in Jiangsu have made creative admission packages for their freshmen students this year.

The admission letter issued by Nanjing University this year is packed in a red box, which contains many cultural and creative items for the freshmen students.

Covered under the admission letter is a "black box". The "black box" has a colorful cover with a blue whale pattern, which is the mascot of NJU, on it.

Inside the "black box" is an arc-shaped space full of stars. On the inside of the arc-shaped box is the basic law of calculation, the Pythagorean theorem, the law of universal gravitation, as well as a number of stars named after alumni of NJU printed on it.

There is a unique setting at the bottom of the box that can light up the stars in the box.
