It took three years to learn the scriptures, and the Tang Priest walked for fourteen years. Li Shimin, why don't you hurry?

Because he never thought there were monsters in this world. According to Tang Priest's original plan, three years is enough for this trip, as long as you don't slack off and don't waste time on fun. Moreover, according to Tang Yan's original words, it takes three years at a time. According to normal thinking, he certainly didn't think that he could become a Buddha and fly after learning the scriptures. That is to say, the original plan was to arrive in the West in one and a half years and return in one and a half years.

The Journey to the West didn't explain in detail why Tang Priest was confident that he could reach the Western Mountain in a year and a half, but judging from his naivety, it was obviously his own imagination, instead of carefully calculating the distance and calculating all kinds of accidents that might be delayed on the road like modern route planning. According to the technology of Emperor Taizong's Li Shimin period, it is obvious that Tang Priest's estimation of the distance of the journey is wrong. Because if this one-way time is on the road except eating, drinking and sleeping, there is no obstacle, then the possibility of reaching the Western Heaven is slim.

To put it bluntly, the so-called? It takes three years to learn from the scriptures? It's just Tang Priest's personal estimation out of thin air. As for what he estimated by cognition, there is no textual research. I can only guess that it was such an idea at that time, so I just said it casually. I'm afraid in his mind, the world is not the land of kings, and Lingshan in the west is probably just a little west of Datang. Three years? Eat, drink and be merry is enough.

As for later facing the reality, just out of the capital, two attendants sent by Li Shimin of Emperor Taizong were eaten by monsters, and then all kinds of dangers and hardships along the way made Tang Yan unimaginable, and even almost lost in all kinds of temptations, giving up the career of learning from the West. All these make Tang Priest feel that he is grateful to learn from the scriptures in 14 years, so why complain!
