Tianyin Qinfang, whose name is taken from the "sound of nature", was produced by Yangzhou City's representative intangible cultural heritage project "Guqin Art" (Guangling Qin School) in the 1990s. Mr. Lu Rong, the representative inheritor and Yangzhou arts and crafts master, was founded in the ancient city of Yangzhou. For more than 20 years, Mr. Lu Rong has been studying the art of guqin cutting, communicating with famous guqin masters and teachers from all over the world, learning from others' strengths, and striving for excellence. After years of painstaking research and development, he has developed an increasingly perfect guqin cutting process and is quite mature. The skill of playing the piano. In 2010, Lu Rong received personal guidance from Mr. Gong Yi, a leading figure in the guqin art world. He deeply combined the qin-playing skills with the qin player's performance, giving Tianyin guqin an extraordinary artistic spirituality without the craftsmanship. At the beginning of 2014, two rare pianos, "Liu Yu Zisun Geng" and "Daya" were released, which were highly praised and became the representative works of Tianyin Qinfang. Tianyin Qinfang then launched the "Jinshitang" Lu Rong's hand-cut series. Jinshi is a homophone that means "gold stone". The sound of gold and stone was originally the sound of copper and jade, crisp and beautiful. Later generations borrowed gold and stone to refer to music in general. Therefore, Mr. Lu Rong used "gold and stone" to inscribe himself on the piano. To this day, Lu Rong's personal guqin playing has been highly recognized by the qin world.
