In "Journey to the West", what exactly does Sha Monk carry as his burden?

When we are reading the novel "Journey to the West" or watching the TV series "Journey to the West". I am always curious about Sha Monk, who carries a burden all day long. What exactly does he carry in his burden?

In fact, we can see from the TV series that the burden shouldered by Sha Seng was actually there from the beginning. However, at the beginning, Tang Seng only had one disciple, Sun Wukong, and then it was Sun Wukong who picked it. After having Zhu Bajie, naturally it was The second senior brother Zhu Bajie was born, and finally there was Sha Monk. From then on, Sha Monk has been carrying the burden. In this book "Journey to the West", we are deeply impressed by the unknown Sha Monk carrying the burden and following Tang Monk to the west to learn scriptures. .

We can simply know something about it in the ninety-seventh chapter of the original book of "Journey to the West". The four masters and apprentices were framed, and the executioner threatened him for money, insulted and kicked Tang Seng, and Tang Seng died. Sun Wukong was asked to give the valuables in the bag to the small officials, but where did the poor monks get the money? There were only a few worthless cloths in the bag, and some customs with the flower seals of various countries. The only thing in the bag was that The cassock was given by the King of Tang Dynasty.

From here I can know a little bit that these things are in the luggage carried by Sha Seng.

In fact, there is no need to write out everything Sha Seng Tiao did. It is not necessary because it is not the focus of the full text of "Journey to the West". Drifting is not the most important core character in the whole story. Although he is very important, it is not that important, so Wu Chengen may not focus too much on him.

But what did Sha Seng carry? It was just the same luggage as us ordinary people. It was a little different from everyone else. Maybe it was because they had some extra paperwork in their luggage. After all, they were going all the way. I have traveled through so many countries to learn from my experience.
