There can be NO DOUBT on Chinese contribution to Humanity. It is the only nation on Earth with RECORDED 5,000yrs of Humankind history - good & bad, thru various dynasties as each mortal emperor sought to elevate lives but sadly, power corrupts & absolute power corrupts absolutely, proven thru the records.
The last golden age of Han China was in the 15th century, thru the sacrifices & almost impossible hard work by the enlightened emperor - the Ming. In the end, the adage that power corrupts is proven thru, & China was ruled by the self serving exclusive Manchus, & WORSE - by the devil Mao who presumed himself as a god on Earth thru the Cultural revolution that saw the END of Chinese innovation....
The insignificant nobody me can still see the innovative works of past Chinese workers, most evident - being an Asian, in Malacca let alone in Beijing.
Cabinets made of exquisite red wood intricate carvings & laquer that lasted when the Chinese arrived to assist the 1st monarch of Malaysia in the 15th century till today...There is SO MUCH in China's evolution & progress since recorded history, but sadly, the devil Mao ended it all, along with their fervent communist supporters whom still pray to Mao & his horrific ideologies as a god on Earth even today...
We are ALL Humans first before ideologies separates us. NO mortal is a god regardless of race, language or religion. We are ALL flawed & NOT perfect. Thus may Humanity NOT be fooled & pray to mortals or listen to their advices which will only lead to Humanity's extinction WITHOUT any thoughts, free discussions, debates to find solutions to progress & evolve....
