You are right, technology makes human strong. But grasping technology requires hard work, while working too hard doesn't promote human health, as I have said above. If human has evolved to be adapted to being strong, working hard should be good for human health.

But is there any evidence that can prove that the parent knows this or doesn't know this?

Is what I've said in the words below the title right (the grey words)? This is my personal opinion and I want your response for what I've said.

That's what I've forgotten to correct. I copied a sentence what a user said in another page where the topic "Should a teacher hit students" was raised.

The "be slapped" ought to be changed to "be punished".

I am a Chinese. I'm very sad about our nation's optimism. I believe that our nation being optimistic is because our nation is stupid.

People all over the world know one feature of Chinese people: As long as anything exists one positive aspect, Chinese people will be totally blind to all the negative aspects. I think this is the most correct description of Chinese people's property. Chinese people are very "lack of lash".

The quotes in The Analects, which superficially sound like what great masters' say, are essentially chicken soup for the soul. Influenced by Chinese traditional culture, Chinese people are teached to view things positively from very young, evading to face any negative thing. Such most idiotic words like "How good!" are said and written in compositions by Chinese students many times every day without being felt to be idiotic, and teachers read these idiotic words without feeling idiotic. That's a clear proof of Chinese people being stupid.

Viewing Chinese teachers, professors and other teaching workers, one phenomenon is very clear: When they scold, their speech are usually intermittently blocked; when they praise, their speech are f*ckingly fluent.

You haven't answered my question. I am asking if Chinese like praising because they are f*ckingly optimistic and Westerners like criticizing because they are more pessimistic than Chinese.

You haven't answered the question. Can "Rome is a city in Latinia" prove it was not invented by Romans? Was it invented by Romans or other places in Latinia?

No, Greek alphabet is not derived from Latin alphabet. Latin alphabet is derived from Greek alphabet.(My native language is not English. I may misunderstand some of the meanings.)
