Li used to be a special effects artist before becoming a teacher in 2007.He recalls the first time he taught a lesson, he was too nervous to say much, but just did illustrations on the computer instead.

"It took me a year to get rid of my nerves and, luckily, the students gave me much support and encouragement," Li says. "They could see that I was nervous, but they believed in my knowledge and skills, so they would comfort me with their expressions or with small gifts."

Most of Li's class are college students who want to learn more practical skills in the area of postproduction before they get a job.

"I'm glad to see that all my students are passionate about films and they like making digital art. Seeing some of them take part in the postproduction work of films and TV series gives me a rewarding feeling."

Li has a passion for film, too, and has plans to make some short films.

The question is, however, how will they taste when they're finished?
