Who are the two people in the amber in the last chapter of Tang Brick?

The first chapter of Brick of the Tang Dynasty reads as follows

A pheasant jumped out of the grass, stunned Ye Yun, and woke up from a daze. The eyes are smart again, and the mind is awake from ignorance. "Where is this?" Ye Yun asked himself, ten minutes ago, he was looking for the two missing foreigners on the Gobi with his backpack. Now, he is naked and standing on the grassland. This is beyond his comprehension. Look at the scorching sun overhead. Still familiar. ......

And the last chapter-Amber reads as follows

Lee Tae proudly said to Ye Yun, "I haven't wet the bed for three days. Thank you for sending me two huge pieces of amber. It's really calming.

Just why are there two grotesque conference semifinals in amber? You and I both know that it takes many years for amber to form. According to your theory, amber and the keel in the academy should be the same age. Who was there then? "

Ye Yun looked sadly at the distant mountains and said nothing. Some words can't be said to be dead. Some words are only suitable for being taken into the grave. Some things can only leave clues like slush and claws to others. It becomes boring when you say it, and the evidence is actually irrelevant. The most beautiful thing is actually a guess. Only colorful speculation can create a new world. Ye Yun is not going to tell Lee Tae that he plunged into the Tang Dynasty because of these two bastards. ...

It can be judged that the Hu people in the two amber in the Tang Dynasty were the two foreigners who were first searched and rescued in modern times.
