    TIANJIN, Dec.12, 2018 (Xinhua)—Striking Chinese gongs(锣) for 50 years, Liu Zibin, a 70-year-old folk artist in Tianjin Municipality, is eager to introduce the traditional musical instrument used in Chinese opera to more people.

Liu became addicted to Chinese opera in his childhood when his grandfather frequently took him to watch performances. At the age of 13, he joined Hebei bangzi training team. Hebei bangzi is one of the oldest types of Chinese opera in northern China, which became popular in the Qing Dynasty. It is a traditional Chinese opera combining music, vocals, dance and acrobatics(杂技).

“It took me hours to practice the basic skills of gongs,” he said. “This round piece of metal can help performers on the stage to express joy and sorrow when hit by a stick with different rhythms, so I must bear in mind all kinds of rhythms(节奏) for various situations. For example, striking gongs with a quick tempo(速度) can create a tense atmosphere for action scenes.”

In the 1960s and 1970s, the reorganization of opera troupes in Tianjin forced many members to switch their jobs to those in factories. Thanks to Liu’s brilliant skills, he was fortunate enough to go to one of the three biggest Beijing Opera troupes in Tianjin to continue his gong life.

Ten years ago, Liu retired, but he still goes to an opera tea house almost every afternoon to strike the gong for opera performances. In 2006, Hebei bangzi was listed into China’s national intangible cultural heritage. However, he worries about maintaining the art as fewer and fewer youngsters are learning percussion(敲打乐器), especially gongs. “People who strike the gong stay behind the scenes. It is hard for them to gain fame and fortune,” he said. Although many amateurs(业余爱好者) have learned from Liu over the years, some gave up easily. “It’s a bit dull and boring to continuously strike a gong for 40 minutes at the practice stage. It requires patience. Few can bear the hardship,” he said.

Various kinds of Chinese gongs are neatly placed at Liu’s home. He is waiting for more people to take over his career and spread the traditional Chinese art.
