60 years of change - 1 became 10.

60 years of change - 1 became 10.
60 years ago,
When I was a child,
Noisy mt parents , I want 1 dollar.
1 dollar can buy 10 lollipops.
2 dollars can buy a popsicle.
4 dollars can buy 1 comic book.
5 dollars can eat a bowl of large noodles.
I work 2 years , can buy a house .
Now, 60 years later
buy 10 lollipops need 20 dollars.
buy a popsicle need 10 dollars.
buy 1 comic book need 75 dollars.
eat a bowl of large noodles need 60 dollars .
buy a house, need work 20 years.
And now the 10 yuan coin and the previous 1 yuan coin
Almost the same
so sya, 60 years , 1 change to 10 .
