Shenzhou-11 reached the space lab after two days. The spacecraft adjusted its position four times at differences from Tiangong-2.

These adjustments were done at 5 kilometers, 400 meters, 120 meters and 30 meters.  Shenzhou-11 needed to cut its speed to 0-point-2 meters per second to dock with the lab successfully.

To us here on earth, Shenzhou-11 and Tiangong-2 were travelling at 7-point-9 kilometers per second when the rendezvous happened.
