What is the origin of the name Shekou in Shenzhen?

The first time I heard the name Shekou was 15 or 16 years ago. In a social program about drug addicts and drug addicts in Shenzhen, there was an example of a girl who slipped in a bar in Shekou abusing ecstasy. . . It seems that after that, I was still a very simple northern rural pupil. I was shocked to see my sister devastated by drugs, so I remembered the name Shekou. I guessed at that time, is it because there are many drug addicts in this place, which is chaotic, so it is called snakehead? Like a chicken head. . .

Later, I found that there were maps of various provinces in the geographical atlas issued by the school, so I went to Shenzhen on purpose, and then I really saw Shekou, only to suddenly realize that Shekou was a peninsula extending into the sea with a hole in the middle of the peninsula. From the outline, isn't it like a snake head with an open mouth? It's so vivid. So I'm almost sure that the name Shekou comes from the terrain outline. . .

Many years later, after graduating from college, I went south to work in Shenzhen. It's really something that a small hillbilly didn't expect two thousand kilometers away. . .

Look at the map of Shekou again. It doesn't look like a snake anymore. It may be the result of years of reclamation. .

So after all this talk, it seems that I still haven't confirmed the origin of Shekou's name, right? Because I don't know. But for the time being, I still insist on my childhood point of view and name it after the shape of the map. what do you think?

With the change of time, many things have undergone earth-shaking changes. What was once taken for granted has become hard to find after many years. Just like the origin of the name Shekou, if we look at the map many years ago, we should have guessed what it is. But today, many years later, this small problem has really become a problem worth studying. Some things, some people remember, can be elegant. And some things, with the erosion of time, gradually, really forgotten.
