In 2019, Yan began participating in various international violin-making competitions.

"There are more than 100 processes in the violin craftsmanship and each must be meticulously executed," he said. "Violin making involves many crucial processes that determine the instrument's sound and quality, such as crafting the top and back plates."

To ensure the violin achieves a balanced resonance, Yan designed the top and back plates with 68 points on each.

"I measure the thickness of each point with a micrometer," he said. "Excellent violin makers need to adhere to craftsmanship standards strictly and undergo repeated adjustments to achieve the instrument's desired acoustic state."
