In the long river of inheriting and preserving intangible cultural heritages, people have encountered numerous challenges, especially in this rapidly developing era. Fortunately, there are still many individuals who persistently make efforts to safeguard it.

Chang Yangyang is such a person. As an inheritor of intangible cultural heritage, he once worked at a factory. Although he had learned the craft paper-cutting from his grandmother since childhood, in the eyes of Chang’s parents, a hobby was far less precious than a stable job. They didn’t change their minds until he won third prize in a national paper-cutting competition in 2010. This opened a new door for him in paper-cutting, which strengthened his determination to continue his career in the craft.

In addition to practicing skills diligently, Chang thought more about how to promote the Mengjin paper-cutting culture and let more people know about this intangible cultural heritage.

In his early years, Chang conducted local training and salons. Later, He tried Douyin live-streaming. At first, Chang was shy. But gradually, he became more familiar with it and learned to interact with viewers. In this way, he expanded his audience and followers from dozens of people to hundreds of thousands.

The young paper-cutting artist and instructor hopes there are more young people learning the art. It is for this reason that he currently teaches the art of paper-cutting at several local primary schools, Chang says his life dream is to establish a paper-cutting museum one day so people can learn more about the art form and grow to love it as much as he does.

With more young craftsmen like Chang injecting fresh energy, the intangible cultural heritage will be able to continue sharing the same clear wind with mountains and forests, and the same bright moon with rivers in the future years, moving towards eternity.

Is there a need to rebuild the Old Summer Palace? In reply to such a proposal from a national lawmaker, the National Cultural Heritage Administration said there was no such need.

The Summer palace on the outskirts of China’s capital is a tranquil park with canals, bridges, pagodas, ginkgo tone ruins, and a few traditional buildings. Despite still covering a large area, the site today represents only a shadow of what stood before.The ruins have long been a potent symbol of China's"humiliation"at the hands of foreign powers.

In 1860, British and French troops looted and burned the Summer Palace in response to the killings of 20 European emissaries during the Second Opium War: Forty years later, it was further damaged by a coalition of foreign nations. Historian Bernard Brizay described these acts of cultural destruction as equivalent to invaders blowing up the Palace of Versaille (凡尔赛宫), looting thousands' of priceless artworks from the Louvre((卢浮宫), and burning France's national library to the ground。

Since rebuilding the Old Summer Palace was first proposed in 1980, there has been an ongoing public debate about whether its ruins should be left to stand as a permanent reminder of China's dark history. The state-run newspaper Guangming Daily called the remains of the Summer Palace "the most realistic teaching materials" for instilling a patriotic education. "Though humiliating, they cause people to think, "an author wrote. “They use a cruei reality to tell all Chinese people: Those who fall behind are struck down, while the strong rise and prosper.”

Those in the rebuild camp want to recapture old glory, but they don't understand the importance of cultural relics. A ruin like Yuan Ming Yuan is a historical record. In this case the history includes its destruction by fire. If you rebuild, you erase the record.

Noah Higgs hated learning Irish in school. He hated the way it was taught, overly formal and disconnected from ordinary people’s lives. Most of all he hated the effect the lessons had on his fellow students’ willingness to speak the language. But the Dublin native never lost his love for Irish, nor his opinion that more people should be learning the language.

Today, almost 40% of the 7,000 languages spoken worldwide are endangered, according to the United Nations. More are going extinct every year. It was once widely feared that the Internet revolution would accelerate this decline. If developers and smartphone manufacturers aren’t willing to invest in supporting minority languages, that would cut off people who speak them from an important way to communicate and trap those languages in the past.

Higgs, 23, though, is one of a small group of educators and activists reinventing how minority languages are taught and preserved online by using cutting-edge technology.

When he was 17, Higgs had a “crazy teenage idea”. He had begun using Duolingo, a mobile language-learning app, to study French, and wondered if the creators had considered adding support for Irish.

At the time in early 2013, there were five languages on Duolingo, the smallest of which, Italian, has an estimated 67.9 million speakers worldwide. By comparison, at its height in the 18^th century, there were an estimated four million Irish speakers. Today the figure is closer to 1.2 million.

“I didn’t get a reply,” Higgs said.

But his email wasn’t ignored. Inside Duolingo’s open-plan, Silicon Valley-style headquarters in Pittsburgh, Pennsylvania, change was going on. Within five years, the language startup would build a library of over 30 languages, including some of the most endangered on the planet.
