Suppose, whatever for certain you are talking about, maybe because that's past. Because we will never go back to the conditions of those times.
That put, past is talked about and tied in in many articles. Including in the one you replied to.
"Fua, why is it no one ever talks about or remembers how things were before the boom times?."
Repeat a bit
As the East Asia scholar Ezra Vogel wrote in 2019, “No countries can compare with China and Japan in terms of the length of their historical contact: 1,500 years.” As he observed in his book China and Japan, the two countries maintained deep cultural ties throughout much of their past, but China, with its great civilization and resources, had the upper hand. If, for most of 1,500 years, Japan could live in peace with China, it can revert to that pattern again for the next 1,000 years. However, as in the famously slow Kabuki plays in Japan, the changes in the relationship will be very slight and incremental, with both sides moving gradually and subtly into a new modus vivendi. They will not become friends anytime soon, but Japan will signal subtly that it understands China’s core interests. Yes, there will be bumps along the way, but China and Japan will adjust slowly and steadily.
India and China have the opposite problem. As two old civilizations, they have also lived side by side over millenniums. However, they had few direct contacts, effectively kept apart by the Himalayas. Unfortunately, modern technology has no longer made the Himalayas insurmountable. Hence, the increasing number of face-to-face encounters between Chinese and Indian soldiers. Such encounters always lead to accidents, one of which happened in June 2020. Since then, a tsunami of anti-China sentiment has swept across India. Over the next few years, relations will go downhill. The avalanche has been triggered. .. https://investorshub.advfn.com/boards/read_msg.aspx?message_id=166202722
That goes a great deal between past, present and future.
