Protons are mostly princes or important grandsons of Wang Shizi or vassal States. Judging from the actual situation in history, this kind of guarantee has little effect, and no country will sacrifice its national interests because of protons. In addition, the battle for succession to the throne is fierce, and the lack of a competitor may be exactly what people expect. The gentleman said, "If faith is not sincere, quality will be useless."
The keepsake in history is very famous. Qin Shihuang's father, an alien, touched the dragon and said Queen Zhao.
The proton exchange between Zhou and Zheng should be the beginning of proton exchange in history. But in the whole Spring and Autumn Period, there were only six cases of protons, and it was after Jin Wengong and Qi Huangong. It was not until the Warring States period that it began to increase. There are many Qin States, which shows the military status of Qin State at that time.
Proton's treatment is far less than that of the princess who married in the past. This can be seen from beating strangers. When Lv Buwei helps win strangers, the situation of winning strangers is very bad. Of course, it is also because Qin has repeatedly sent troops to attack Zhao despite its protons.
Some countries treat protons with courtesy, but most of them are superficial. Think about it. The sons who are usually sent to be protons are almost unworthy or neglected sons, and most of them are concubines. It is usually a symbol of the armistice between the two countries. Both sides are not stupid, and they must know that quality is not important. Moreover, protons are always taken hostage in two warring countries and are often in a precarious situation. The two countries really fought, and protons were killed first. Very sad. Protons usually live in the capital of an enemy country, so that they can be taken care of and prevented from escaping.
