Before its maiden voyage in October 2021, the cruise vessel had gone through 453 emergency rehearsals, and another 972 emergency exercises have been completed since then. A pandemic prevention and controlling system has also been established on the ship, so as to ensure the health and safety of guests and crew members on board, while ensuring the comfortability of the cruise traveling experience, according to Liu Fei, staff captain of the China Merchants-Yidun.
