The only works handed down by Mozi and his followers are Mozi. The book was originally 7 1, and there are 53 existing books. This book is mainly a collection of Mozi's disciples, Mozi, who recorded Mohist thoughts and deeds. Because Mozi and his followers can bear hardships and stand hard work, be brave and fearless, take part in production and be keen on experiments, Mohism not only has an important influence in thought, but also has great achievements in science and technology. Mohism's exposition on science and technology includes mathematics, mechanics, acoustics and optics. , mainly preserved in the Mohist Classic, and Mo Jing is a part of Mozi.

1. In mechanics, Mohism gave a scientific definition of "force". In the research of lever balance, the concept of moment is actually put forward, considering not only the magnitude of force, but also the length of arm. It can be said that Mohism has found a condition of leverage balance.

In addition, Mohism has a profound discussion on movement and time, axis, slope, ball movement and buoyancy, etc.

In acoustics, the outstanding achievements of Mohist school make solid acoustics and sound skillfully used in military affairs.

2. In optics, Mohist studies more. They completed the first hole in the world in the imaging experiment.

In addition, many studies have been made on the concave-convex imaging phenomenon of bird ink shadow, umbra and penumbra objects.

From the research of Mohist physics, although some aspects are still primitive, many of them are consistent with the experimental results of modern physics. It is believed that Mo Jing was the work with the highest level of natural science in the world at that time.
