Zhang Yi is Chinese reporter in Singapore. In 2022, a woman with grey hair living nearby visited him. The woman introduced (she) as Sarah. She asked Zhang could help look for her pen pal who was from China.
Duan Chun was Sarah's first Chinese pen pal. They (write) a lot of letters and shared the colorful school lives sixty-one years ago. All the letters were kept by Sarah. They were full her sweet memories. However, Sarah hadn't received any letters from Duan for many years. It seemed impossible to find a person after such a long time, 91 Zhang promised to do his best. He posted some of Duan's black-and-white (photo) and their stories on the Internet. To his joy，many lovely strangers joined him in searching for Duan. Although they went through lots of trouble，they never stopped trying. A few months (late), the two pen pals finally began to communicate with each other again. They were so excited that they decided (meet) in China. Sarah prepared a gift for Duan to celebrate her (seventy-five) birthday.
It was with the help of so many caring people and high technology that the cross-country friendship was able to continue.
