0 1. In order to publish the ancient times, if the ancients wrote poems on paper, they eventually wrote piles of paper, and finally there was only one cabinet. Isn't it sad that the poem I worked so hard to come up with was not published? But when the ancients wrote poems on the wall, they would not be covered up by the passage of time. If you write it on the wall, it is equivalent to writing it in a newspaper. Everyone can enjoy it and publish it. So when your poems appear in the streets, everyone knows that you wrote them, not others.
In order to spread the ancient times, technology is naturally not as developed as it is now. It is even more impossible to have a circle of friends or Weibo, so when you write a poem, you must want to let more people know. Writing on paper may not achieve this effect, but writing on the wall is different. No matter where you write on the wall, someone will pass by, from one word to ten words, from ten words to a hundred words. Slowly, more people will know your poems and increase your exposure. If it is a good poem, it can be passed down forever and remembered by future generations.
03. In order to help publicize ancient times, there are many restaurants and the like. In addition to fighting for taste, restaurants will also fight for popularity. This truth must be known to everyone. If our restaurant once had a great writer to eat here, what's more, he left poems on the wall. Presumably, many people will come here because of this. Whether enjoying or eating, it will bring a certain amount of people to the restaurant and help the business to prosper. From this perspective, the ancients wrote poems on the wall to help the store publicize.
To sum up, the ancients wrote poems on the wall for publication, circulation and publicity.
