80-year-old’s love of teaching inspiration to all

Where are the other 98 percent of the 1 billion used cellphones? Most of them stay in people’s homes and it is common for each family to have one or two used cellphones left in a dusty corner at home.

That’s a huge waste of resources. The market for recycling used smartphones has enormous potential that is yet to be exploited. There are huge opportunities for recycling enterprises.

Data show that about 150 grams of gold, three kilograms of silver and 100 kilograms of copper could be extracted from every ton of used cellphones. Besides, some parts of the used cellphones, for example the battery, pose a risk to people’s health and the environment.

There are several reasons why people are reluctant to

recycle their used phones. Some worry that the information stored in their memories might be recovered, while some feel the price of selling used smartphones is rather low.

With smartphones now the main product in the market, people are changing their phones more frequently. Neither the electronics recycling industry nor users were prepared for such a change.

To tap the potential of recycling cellphones, the government could offer subsidies to recycling companies, so that they can raise the price they offer to purchase used cellphones. This would encourage more people to sell their used phones for recycling. It is time authorities considered this possibility for the benefit of all.

taught by Zhang Zhujun, a professor of chemistry at Shaanxi Normal University, who is now in his 80s, has gone viral online, because of his humorous teaching style and the encyclopedic knowledge that he has acquired over nearly 60 years of teaching. Shaanxi Daily comments:

His classes are always crowded with students from various departments, even those from other universities.

Students jokingly say that Zhang has the ability to make a student majoring in literature change to chemistry.

Zhang suffers from some chronic diseases and has four stents in his heart, but his love of teaching means he can still instill in students a passion for chemistry.

Zhang’s enthusiasm should remind other professors obsessed with their well-paying research projects or publishing theses in academic journals in pursuit of promotion, that teaching is their primary task.
