A crowd of criss-crossed kids sit before her as she places her fingers over the soundbox of her traditional erhu instrument and concentrates on her demonstration: “Baby Shark” begins to fill the room.

The Mid-Autumn Festival was held at the Coolidge Corner Library on Saturday Sept. 21 from 1-4 p.m. The annual event celebrates the holiday of the same name, which is celebrated in east and southeast Asia and took place on Tuesday, Sept. 17.

The event had multiple stations set up throughout the space: an area for calligraphy, where onlookers could watch Chinese characters be written and choose one to take home; a long table with various crafting tools for lantern decoration; and a corner where double egg yolk mooncakes with lotus seed paste were served along with juices and citrus fruits.

The opening activity was a performance from the Greater Boston Chinese Cultural Association’s Chinese Music Ensemble, who performed songs using various instruments—including the erhu, pipa, liuqin and bamboo flute. The youngest in the ensemble was nine years old, the oldest around 70, and many in the group are family. Conductor Chi-Sun Chan said that their diversity and closeness help them prepare and give everyone a moment to shine, and that he and the ensemble aim to educate the audience on Chinese culture and history.

“I hope they will learn about Chinese culture, like the Chinese instruments, and also how the Chinese music sounds,” Chan said. “The [music] style is different from the West, and also the way that the music is played is also a little different.”

Library staff member Shirley Yang said that the majority of organizing for the event came from staff members who were putting in extra time and work, and that the turnout for the celebration of the holiday was exciting.

“To me, the festival is mooncake and lanterns, so [the staff and I] are happy,” Yang said. “I hope that people will know that the library is here, that we have all these events offered.”

The event drew a multicultural turnout, and French, Hindi, Cantonese, English and Mandarin could be heard throughout the event. However, at the same time, community member Xi Ling, who came to the event with her husband and son, said that the festival was an opportunity for her son to learn about Chinese traditions and meet others from their culture.

“I had a great time with my family and community,” Ling said. “It’s a great event for the kid, so he can see his culture and know other kids.”
