On one voyage when The Crux encountered a strong storm, Beidou noticed a small private boat nearby. Seeing the way it was tossed about by the waves, she ordered her crew to tow the boat to safety — despite the risk that her ship's keel might give way. What little food and water the fleet had left, Beidou shared with the rescued crew as she navigated her vessel onward through the raging storm.

Finally, after several days, The Crux delivered the rescued boat to a safe mooring spot. Grateful to Beidou for saving their lives, the crew of the rescued boat became her loyal trade partners thereafter.
