5. According to the tracking your parcel departed Chine:
2016-06-25 00:44 Beijing airport and left

Has your parcel arrive in India, I don't know because there is no tracking for the parcel yet. But this does not mean your parcel is not moving. It could still be in the Mail Bag in the Inbound warehouse in India and they did not have time to take care of the parcel because there is to much work.

6. You could if you want to contact seller and ask him if the parcel has departed China. He could ask China Post Hot Line: 11185 to find out where the parcel is exactly.

Hope this help.
