1. "Lingering" refers to being addicted to something and reluctant to leave. It can be seen that the object it describes is human psychology and behavior. Therefore,

Therefore, the subject of "lingering" must be a person or an anthropomorphized thing. For example:

Many viewers stopped in front of the painting, nodded thoughtfully, and lingered.

2. Of course, when using "Linger", it may be related to taste, but it definitely cannot be said to describe taste. For example:

People enjoy the sweet-scented osmanthus, suck in the elegant sweet-scented osmanthus fragrance, and never leave. (It’s the people who linger)

These delicacies with a strong German flavor, paired with the world-popular German beer, will leave you with a lingering aroma and linger in your mouth. (The subject of this sentence is "delicious food", but it is followed by "unforgettable", which does not mean that the food itself is unforgettable.)

It can be seen that if you want to use "persuasive" when expressing good taste, or say People linger, or the taste "makes people/makes people/make people" linger.

In short, "Linguan" is used to describe people, not the taste.
