How to distinguish between persistent rainfall caused by warm fronts and quasi-stationary fronts?

A warm front refers to a warm air mass that actively moves toward a cold air mass. The warm air mass slowly climbs. Before the warm air mass passes through, a single cold air mass controls the low temperature and clear weather. There is continuous precipitation after passing through. After passing through, the temperature rises, the air pressure decreases, and the weather becomes clearer. Weather examples: Early spring in South China; and quasi-stationary fronts are cold and warm air masses that move back and forth across fronts that bring continuous precipitation. Weather examples: In Northeast China in August, there are plum rains in the middle and lower reaches of the Yangtze River in early summer, and Kunming quasi-stationary fronts. Generally speaking, it is accurate. Stationary wind causes long rainfall
