What is the background of Grandpa Liang Sishen in "Dajiang Dahe"?

Grandpa Liang Sishen is a rich old man from Shanghai. He has an old single-family house on the Bund in Shanghai. The Shanghai Huating Hotel where Grandpa Liang Sishen stayed was a newly built five-star hotel in 1986. It was located in the core of Xujiahui and was the best hotel in Shanghai at the time.

When we arrived at the hotel, we had to go back to the room to change clothes before dinner, and successfully prepared gifts for our daughter and son-in-law, as well as Liang Da’s meeting gift. At the dinner, Liang Da said, "It is my honor to meet the real Shanghai Lao Keler today."

Old Koehler originally meant large gems. In old Shanghai, diamonds of more than 3 carats were very rare and expensive; so when a jewelry store saw such a good product, the master craftsman in the store would give a thumbs up and say: This old Koehler.

Later, this word was used specifically to describe those old white-collar workers who had returned from foreign countries, had seen the world, and had both modern consciousness and gentlemanly demeanor. In other words, Grandpa Liang Sishen should have been one of the people who went abroad very early, and later became the upstarts in Shanghai. After liberation, he went to the United States, which was already his second trip. From my grandfather's side, Liang Sishen may even be the fourth generation rich and the fifth generation rich.
