Nick was born with no arms or legs, but the brave 32-year-old man plays football and golf, swims, and surfs. Nick has a small foot on his side, which helps balance and kick. He uses this one foot to type, write with a pen and pick things up between his toes.

“I call it my chicken drumstick,” joked Nick. “I’d be lost without it. When I get in the water, I float because 80 percent of my body is lungs and my drumstick acts as a propeller (螺旋桨).”

When Nick was born, his father was shocked. His distraught mother cried all the time and even couldn’t hold him until he was four months old.

“It was so hard for them, but right from the start they did their best to make me become brave. My dad put me in the water at 18 months and gave me the courage to learn how to swim.” said Nick.

Throughout his childhood, Nick dealt with many different kinds of challenges. At the age of seven, Nick tried out some specially designed electronic arms and legs, In hope that he would be more like the other kids. But Nick realized that even with them, he was still unlike other kids at school and they were too heavy for Nick to operate. So in the end, Nick gave up these electronic arms and legs.

“When I was 13, I read a newspaper article about a disabled man who had managed to achieve great things and help others,” said Nick. “It was so cheerful for me that I decided to use my life to encourage others, and not to get angry about what I don’t have.”

“I tell people to keep on getting up when they fall and to always love themselves,” he said. “If I can encourage just one person then my job in this life is done.” By now, he has visited 35 different countries, touring the world as a helpful speaker.

On March 20, 2021 the Sanxingdui Ruins in Guanghan, Sichuan drew the world’s attention. Chinese experts said that they had found more than 500 cultural relics （文物）in six places at the site. It can date back over 3, 200 years. The relics include bronzeware（青铜器）, gold and bronze masks, ivory, jade and textiles.

Experts first discovered the Sanxingdui Ruins in 1929 and believed that they are the remains of the ancient Shu Kingdom. This kingdom was a center of civilization along the Yangtze River. In 1986, experts discovered two places that were used for sacrificial ceremonies. At that time, over 1, 000 relics were found, including bronzeware, face masks and bronze trees.

The discovery of Sanxingdui raised an important question about the beginning of Chinese civilizatlon. The ancient Shu civilization that built Sanxingdui is believed to be one of the earliest examples of Chinese civilization. The site, along with the Liangzhu and Shijiahe sites along the Yangtze River, shows that it might not only be along the Yellow River Basin in the north of China.

The newly-discovered relics are similar to those found in 1986, as they also include bronze trees and bronze masks. They further support the idea that they were used for sacrificial purposes.

New kinds of cultural relics have also been dug up. For example, experts found a kind of special relic, zun, which was used for holding water or wine. They also found cong—a relic commonly found at the 5, 000-year-old Liangzhu Ruin in Zhejiang Province.

“These relics show that the Sanxingdui site had a close connection with Central China, but it also marks an original ancient civilization in Sichuan with strong creativity,” said Chen Xiandan, a member of the project. Now, more and more people are interested in studying the Sanxingdui Ruins and all of us hope that people can find out more new things and explain the secrets about it. So people can have a better understanding about the history of China.
