Hey,

You can use China post international large package service to send your parcel.

From China to India, two ways are available:
By Air: Up to 1kg, it costs RMB 155.6 and for every additional 1kg it costs RMB 57.7.
By Surface (ship): Up to 1kg, it costs RMB 111.7 and for every additional 1kg it costs RMB 13.8.

So, if you choose the first way, you should pay about 900 RMB and the second way about 290.

For Air Parcel, your package will arrive to India within 10 days. But by surface, it needs one or two months. That's the difference. Hope it helps. You'd better go to the local China post office to make sure the price is right. I just found these information online.
