Chapitre 296: The big boss of Beijing University's Mathematics Department gave Jiang Xinyu two head-on blows!

President Yan, old master Jiang, and Yang Hua had a good conversation.

He added master Jiang on WeChat, and then went to yang Hua to add her on WeChat.

"Teacher Yan, I don't have a WeChat." Yang Hua took out her phone.

She had always been in the thousand people village and was almost isolated from the world. She mainly relied on Meng Xun's WeChat to contact Meng Fu.

"Come here, I'll give you the next one." Meng Fu extended her hand.

Yang Hua handed the phone to Meng Fu.

Master Jiang looked at the phone in Yang Hua's hand. It was similar to Meng Fu's. It was black, a little thick, and there were some scratches on the outer shell. It looked like it had been used for a long time.

Master Jiang couldn't help but remember that he had bought a new phone for Meng Fu, but Meng Fu had never used it.

Meng Fu sent Yang Hua a WeChat message.
