In late November, with the participation of onshore troops, surface ships, submarines and air officers, several new warships from a destroyer military unit of the South China Sea fleet launched a week-long targeted anti-submarine drill, furthering the fighting capacity of the participating units.

According to Hu Weihua, the unit leader, more than 10 tasks were covered during the drill. In the process, participating forces simulated circumstances that would exist on a real battlefield. The exercises were intended to improve coordination between officers and soldiers, as well as the strategic skills of the commander. The two teams practiced dozens of effective strategies during the drill. Afterward, the participants came together to discuss and analyze the experience.
