There are many signboard companies in Beijing, and everyone's appreciation level is different! My signature was designed in Liu Yun Signature Design Studio and introduced by my colleague. He will teach you how to write until the design is satisfactory, and there is a personal studio, which is quite reassuring! I've designed it for free before, and it doesn't feel good. Or a penny for a penny. Liu Yun's signature is on Zhichun Road, Haidian. I can't remember the exact location. If you want to go, call first.
