They surveyed over 300 primary and middle schools in Xiongan as a pilot area. They then proposed a comprehensive solution based on common challenges, such as shortages of class content, qualified instructors, hardware and stages.

They've focused on training teachers instead of training students directly, as has been tried before.

The program takes advantage of Tencent's technologies and music and video platforms to maximize the training's coverage, with online classes featuring top performers, such as one by Lang Lang.

The charitable program has also engaged a number of high-level art institutions, such as the Central Conservatory of Music and Capital Normal University in Beijing.

A volunteer team from Capital Normal University's music college provides online tutoring for teachers and students every week, including web classes and teacher assistance.

The recent concert was a good example of the campaign's achievements.

Three choirs of students from schools in Xiongan performed choruses. Other kids performed ballets and piano music, while accompanied by a professional symphony and performances from superstars.

"Regional economies' uneven development makes it harder for rural children to access music, but their passion for it is as strong as anywhere," says Li Gang, deputy dean of CNU's music college, who often travels to Xiongan for the program.

"I was delighted to find that-despite insufficient resources-the teachers and children can create choirs and perform on a par with their urban peers after proper teaching and training."
