I am a sixth-generation ancestral Chinese medicine practitioner. If you are a Tianjin native, you can go to Tianjin Laolaodian Street to inquire about an old Chinese doctor by the name of Mr. Jin. The old gentleman is now in Tianjin and his reputation is well known. The old gentleman is my grandfather – forth generation of the Jin family. The parent generation is the fifth generation and I am the sixth generation.
