Today, an incident impressed me deep.Mom asked me to buy a bag of flour in a shop running by an elderly couple.On the way, it occurred to them that I had no cash with me.
Then I thought I could pay on it with my phone, so I was afraid that they couldn't receive money by phone.After all, they were nearly 70 year old.They might be so much old that they weren't familiar with online service.To my surprise, when I asked an elderly wife if I could pay by phone, she points to the sign on the wall.She said proudly，“Of course, you can scan it！” I felt happy see our advanced society!
