The Huzhou writing brush was recently featured in a video aired during the Chinese Language Video Festival. The festival comes as part of activities to celebrate the 2022 United Nations (UN) Chinese Language Day.

Since 2010, the UN has celebrated Chinese Language Day on April 20, recognizing the language's contribution to the world and encouraging more people to learn it.

In 2021, the Chinese Language Video Festival was jointly launched by China Media Group, the Permanent Delegation of China to the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Chinese National Commission for UNESCO.

It was broadcasted in over 160 countries and regions worldwide, reaching 150 million viewers at home and abroad.

The Huzhou writing brush is a traditional Chinese brush pen that is believed to have a history of over 2,000 years. Many renowned Chinese artists have used the brush to create valuable calligraphy works and paintings.

Crafting a Huzhou writing brush requires over 120 steps. In 2016, the craft was designated as a national intangible cultural heritage item.                                  

The Huzhou writing brush, Hui ink, Xuan paper, and Duan ink slab are considered the "four treasures" of Chinese stationery.
