Dear Friend , We may not learn but China does learn from other countries.
They Learnt Bullet train technology from their Arch Rival Japan and in within 20 years built about 10000 route kms of bullet train tracks in their country which is more than half of the total length of High speed tracks in the world. The have done same with USA and other developed countries with respect to other technologies. They learnt from others and developed if further. They are masters of reverse engineering and the result is before us.
Jocularly...
more... speaking- Bhai Cricket mein, reverse swing bowling par to achche achche aur well settled batsman bhi out ho jate hain. Ye to phir reverse engineering hai. America, European countries, Japan, Canada, Australia sab ek ek karke out hote jaa rahe hain.
Aise lagta hai China ka mantra hai "Development ke liye Kuchch bhi Karega". Hum log "love ke liye kuchch bhi karega" dekte rahe, aur whey log (Chinese) development ke liye kuchch bhi karte chale gye.
Lesson for us : In order to make progress, We must learn the things on their merit irrespective of who says it or who demonstrates it.
