Although it was the first investigation, Han Xiangning had done some homework before the investigation and asked pointedly, "You noticed a cargo ship behind you. Do you know the ship's name? Do you know what type of cargo ship it was?"
"At the time I didn't know it was the 'Yangmi' ship. It was only from the light signals displayed when the 'Yangmi' was anchored that I perceived it was a cargo ship of not too large tonnage."
"Did you use the radio to contact the 'Yangmi' to remind them to keep a lookout?"
"No, not at that time."
"Did you ask the Traffic Control Center via radio what kind of cargo ship the 'Yangmi' was?"
"Not at that time."
"Then when did you notice that your ship was dragging anchor and shifting?"
"Around 1:15 AM."
