As mentioned earlier, the Li family of the older generation in Tianjin may involve several Li families, or even a family will have successive generations. It is known that the descendants of "Tea Plum" are Pu, and the next generation is Jane, which has been verified from the family memory of Han descendants who are also prominent families in Tianjin. The previous generation of the word "Pu" may be the word "Fang", and the first two generations may be the word "Yin". The typesetting of these two generations is also mentioned in the family memory of future generations. Whether it is accurate or not is unknown. Many old Li families in Tianjin are involved in many fields, including salt industry, tea industry, education, minerals, real estate, etc. It is impossible to know exactly which Li family is talking about just from the industry. From the name, it is also the difference between the name and the word, and it is also a question of which is more widely used and more famous, so it is more difficult to judge which generation of the Li family is from the name.
