Fu said the 62-year-old is a sports-lover and loves to do body training in his spare time. Meanwhile, he is a loving and healthy man who is passionate about donating blood without payment.

"The essence of education is inheritance and mutual-learning. I can pass on teaching experience and skills to local teachers while they can help me integrate with local students in an effective fashion," said Jiang.
