A migrant worker who developed five unique math formulas and inspired a university professor has been offered a new job that will give him more space for personal development.

Yu Jianchun, a 33-year-old worker at a logistics company's packaging shop in Hangzhou, Zhejiang province, made headlines recently when he was invited to share his formulas predicting numerical patterns with mathematics professors and PhD candidates at Zhejiang University.

Cai Tianxin, a math professor at the Hangzhou-based university, invited Yu to his class to share his thinking and said he found Yu's calculations inspiring.
