I have personally invited master and expert contemporary violin makers from around the world to join my workshop. We form exclusive partnerships to bring the finest bespoke instruments to players and collectors in China who appreciate the art of violin making. Luthiers of different ages and nationalities became partners of the workshop at my personal invitation based on their Craftsmanship and Integrity.

我以个人的名义邀请全世界的顶尖制琴师以中国区独家合作的方式加入于杰提琴工作室，一起为中国的爱琴之人提供量身打造的世界级乐器。加入的制琴师必须是我主动邀请而来，他们不分年龄，不分国籍。而邀请的条件只有两个： 琴品 和 人品。 他们不分伯仲，请选择你最爱的那一位即可。
