You are yet to explain to me how China is adding an India in 3 years?
At GDP at MER, China's economy stagnated or declined in 2016.
At GDP at PPP, China's economy is only around 2.5 times that of India, and both are growing at roughly the same rates.
Look at Martian's own screenshot.
Look at China's GDP per capita in nominal dollars.
It Declined!
While China's population increased.

Here it is straight from IMF.
China's GDP declined from 2015 to 2016.

Those speeds of growth that you mentioned are for GDP in domestic currency at constant prices.
However, the metric that people use most often, (specially here to show how China is 5 times that of India's size), is GDP in USD at current prices. (Also called nominal dollars)
In nominal dollar terms, China's GDP actually declined in absolute value in 2016.
I'm still waiting
@AndrewJin
Please tell me how China is adding one India every 3 years?
