212 A Round of Praise

Due to Li Guoxiang's insistence, the director had no choice but to ask Li Guoxiang to call Professor Xu over.

Professor Xu had done a lot of research in the academic field of mathematics. Although he was already over 70 years old, he was definitely a leading figure in the field of mathematics.

Although Li Guoxiang's personality was not very good, he still made a lot of contributions to the school. The class he led each year had the highest graduation rate in the entire province.

However, he did not want to offend Jiang Li.

Therefore, Li Guoxiang could only look for professor Xu. If Jiang Li really lied, he could still have an explanation in front of the principal.

As for how to deal with Jiang Li in the end, Li Guoxiang would have to wait for the principal to come back.

In less than ten minutes, Professor Xu arrived.

It was an old man with half-white hair who was full of energy. He wore a pair of glasses and looked very knowledgeable.
