"Row trumpet" is a kind of network terminology, which generally means to publicize oneself or other contents, advertise or promote products on the network through various ways. For example, if a business publishes a promotional poster with a special offer, you can send private messages or comments through various social media to "row trumpet", so that more people can see the offer and attract more potential customers.

In short, the "row of trumpets" can not only get more exposure and attention for products and services, but also may cause negative impacts due to excessive promotion. Therefore, in the network publicity, we should carefully consider the promotion of the way and strategy, to maintain the appropriate publicity efforts, and constantly optimize the promotion effect.
