While other regional puppet shows employ an entire troupe, in Shandong, it's one man's talent that drives the entire performance. Zhang Zixuan goes behind the scenes.

The show starts and gongs and drums sound backstage. Other instruments join the chorus, each different but all in harmony. The shadow puppets appear next, and fierce fighting and acrobatic moves earn applause from the audience.

With such action on stage and a coordinated orchestra backstage, it's natural to assume that there are several performers backstage making it all work.

But this is a one-man show.

The only hero backstage is Fan Zheng'an, a sixth-generation practitioner of the Shandong, Taishan art of solo puppetry. The uniqueness of this art form is best summed up by its other moniker: shi bu xian, literally "busy doing 10 things at once".

"There are two ways to count the '10'. There are the eight percussion instruments, the singing and the puppetry, or it can mean the five senses, all four limbs and the brain," Fan explains.

The gongs, drums, cymbals and wooden knocker are combined into a music machine that can be operated by one man. It is self-made, and people who wander backstage to take a look are often amazed by the ingenuity.

The 67-year-old puppeteer says he was first captivated by the art when he saw his first shadow puppet show at the age of 8. At that time, shadow puppeteers from different regions in China had gathered at the foot of Mount Taishan. They would perform in sheds built from sorghum stalks.

As a child, Fan was a regular guest of one shed. The shed owner was Liu Yufeng and the young Fan thought he was the most magical man in the world. He could make the Eight Immortals in the classic tale Journey to the East come alive on stage.

But the young boy could not afford to buy the tickets which cost 5 fen (less than 1 cent). He sneaked into the performance by hiding among adult legs or making a hole in the sorghum walls. When he got caught, he would linger outside and listen through the walls.

Four years later, when Fan was 12, he dropped out of school and joined Liu on the road as his apprentice.

"Taishan puppetry is especially good at fighting scenes, and its most representative play is about a Taishan hero named Shi Gandang, who captured a lot of evil spirits," Fan is always enthusiastic about his favorite subject and he says he can talk about it for three days without stopping.

"The singing is strongly flavored by the Shandong dialect. And just as Shandong people never hesitate to show their true nature, Taishan puppets are very close to life."
