What is a customs clearance document? Why are these countries obediently stamping their stamps on it?

The customs clearance document is equivalent to a passport. The reason why many countries stamped it obediently is because the country that issued the customs clearance document was very powerful at that time, and the country that held the customs clearance document was very powerful. The person who writes the ultimatum has a distinguished status. When it comes to customs clearance documents, many friends think of Tang Seng in "Journey to the West". Because every time Tang Seng and his disciples went to a country, they would take out the customs clearance document and stamp it with the local king, and it seemed that the king of every country was very happy to stamp it. Next, we will take this perspective from "Journey to the West" Let’s talk about what a customs clearance document is and why the kings are willing to stamp it.

A customs clearance document is equivalent to a passport. With this customs clearance document, you can travel smoothly in a certain country. In the TV series "Journey to the West", Tang Monk holds a customs clearance document. When he arrives in a country, he will take it out and stamp it for the king. Then he can use this small book to roam around the country. Go away, this is the biggest use of the customs clearance document. The reason why the emperor of the Tang Dynasty wanted to give Tang Monk the customs clearance document was to save him from obstacles along the way, and the customs clearance document also had another most important role, That is to record which country he has arrived in. After all, after returning from the Buddhist scriptures, he has to explain to the King of Tang that he has traveled thousands of miles across mountains and rivers and experienced so many countries to collect the true scriptures. This can also indirectly reflect the hard work of Monk Tang in collecting scriptures.

The reason why those countries obeyed and stamped their seals was because the Tang Dynasty was the most powerful country at that time. At that time, the Tang Dynasty's national power was very powerful. It was far ahead of other countries in terms of military and economy. It could be said to be the superpower of that dynasty. Therefore, many small countries must have seen the customs clearance documents of the superpower. I will stamp it obediently. After all, we will continue to have trade and cultural exchanges with this superpower in the future.
