How can I convert CNY to INR?
There are two ways to do so and they are common for all cross country visit...
1.
Not using bitcoin : Have an international debit card (with MasterCard/VISA) from a Chinese bank (most HK banks will offer this). Top up your bank account with CNY. Withdraw INR from any Indian ATM.
2.
Using bitcoin : Have a bitcoin debit card (e-coin.io, AnxBtc, WageCan etc.) and buy bitcoin with CNY to top it up. Use it to withdraw INR from any Indian ATM.
I think you are right.
What I did was carry the greebacks and exchange INR at various rates. 1USD:61INR at airport, 66-67.5 at currency exchange stands(with and without signs)
