Shenzhen Bay Gymnasium is near Shekou Bus Station. I suggest you get off at Guimiao New Village and take No.362 (3 stops), otherwise you have to transfer.

Or to Nantou Bus Station, you can transfer to No.337 or No.382 and go directly to Shenzhen Bay Sports Center.

If you go to Shenzhen Bay Gymnasium on weekends, you can go to futian bus station, which is a bit far, but there is a through train to Shenzhen Bay Gymnasium:
