"When Westerners (for this sake mainly Portuguese and British) came for the first time to China so they realized that Chinese were much less sick then them. "

Which time is this exactly?

Lol. I know I am hogging this thread, butthe subject of invention and dicovery is one of my pet subjects.

Medical science has very much been one of accidental discovery, until the base knowledge was gained.

Physics was different. Physics was all about "why?" Gifted individuals came out of the blue and changed the world.

Engineering followed on, "How can I do this better?"

Philosophy: " Why do you want to?"

China: " We know it already"

A few years back, I was fishing a pond in rural China. Plenty of water in the pond, but the fields the water was intended for were maybe 2 meters above the water level. So every day the old guy and his wife would come out with their buckets and spend most of the day carrying water up in their two buckets.

I thought, "Why not just build a cistern in the field and install a pump to pump the water up? . Because then they could spend the time weeding the field rather than carrying water."

But I was thinking with a western mind. That's why I am so fat and they are so fit and thin.

Same with the fish in the sea. The west developed easier ways to harvest them. So now there is no fish left.

Maybe that old couple carrying the water were really smart.

Because with my thinking, I would end up using the pump to water more fields to grow more crops.

Nah, more crops is good.

What makes me sad, is we can't distinguish the lies from the truth anymore. What if there really was an ancient version of the toothbrush invented in China, use of mold as antibiotic, or genuine documents that prove the Diaoyu Islands belong to China? The truth is lost among all the fabricated lies.

So, in an effort to claim cultural superiority, the factual truth about China's true achievements is being severely obfuscated. People are now inclined to believe NONE of it is true, even if some things might be. China is continually destroying its culture, history and heritage. That makes me a sad panda. Even though I'm not Chinese, I'd love to learn more about China's objective history. But the Mainland, where most of it took place, can't be trusted.

Well, after Galen and Hippocrates, in Europe, it was indeed the Dark Ages until the Renaissance and the translation of Arabic books. And it's not until late 19th century that hygiena became big deal in Europe. In China, well, it was also pre-scientific approach to medecine until the 20th century, with similar results:

A *MAJOR* factor at play was that Chinese people tended to be better fed than Europeans one until the 18th century. Until the 17th century, the average European worker had access to close to half the intake of a Chinese worker !!! Ho, in China, in some cities, some form of public healthcare existed (take that, taxes & welfare haters) Weak, poorly fed people tend to be more likely to be sick and have all kind of chronical issues like skin rash, pain, poor teeth, stunted growth, etc.

With such huge differences, I would rather look at that food intake & life standards issue, rather than pre-scientific shenanigans that are a mix of statistical noise, misplaced national pride, empirical chance findings, and placebo. Ho, and last nail in the coffin : look at the death rate for any kind of plague, pneumonia outbreak, flu outbreak, pre-1900 : TCM, lol. Who got the balls to cure his/her cancer with TCM ?

You stereotyped West by yourself. I would like to know what has West(EU) contributed to the medical sciences until 15th century? Nothing, on what basis are you comparing ancient China and West in a parallel era?

References from what? History? You aren't accepting the very history if written by Eastern writers. There isn't a point to ask for references at all in that case.

I looked for historical Chinese scripts on knowledge about bacteria and germs in 19th Century on the web yesterday, but there are none.

Chinese medicine in that period was based on 'beliefs' more than actual study of bacteria.

Alternative medical practices can be based on an underlying belief system inconsistent with science, or on traditional cultural practices.
