There were no loudspeakers and portable loudspeakers before, and the sound depended entirely on people's mouths. The voice in front should be smooth and clear, and the last voice should be raised and raised. The air foot is in the middle, and the sound may be far away in the alley. In this way, the effect of advertising is obvious.

2. The previous craftsmen all had their own cries.

The essence of advertising is the skill and means of eating by it. Some selling groceries, some repair porcelain, some shave and get a haircut. They are different. But the key is to highlight their own characteristics. Simple and clear. According to the characteristics of simplified characters in the daily life of working people, people will know who is here, what skills they have mastered, whether there is a need at home and what to go out to see. When I was a child, I also heard the crying of grinding the mirror. After ironmaking, sharpen knives and scissors.

3. Call must be tailored to local conditions.

Ordinary small craftsmen only live in fixed places. Dialects were very common at that time. Of course, they must advertise in a language that most people can understand. In fact, it may be a knife, a stick and a scissors, which have similar pronunciations in many dialect languages. On the contrary, verbs can be changed at will as long as the audience can understand them.

There are markets everywhere!

Who doesn't order these necessities? No cooking? No matchmaker? There was no need to cut windows before, mainly by hand. There is no mirror to look at, but I don't know. The previous ironware did not have good maintenance methods and materials, so it was normal to rust and wear.

It is said that the working people made history.

In the final analysis, this is the most economical thing that workers find in the process of work, and it has finally come down. When people shout, they can not only let people know their work, but also save money for publicity.
