It should be pretty good.
Princess Wencheng went into Tibet (then called Tufan), but she did not go alone. According to historical records, she brought 5,500 craftsmen with different handicrafts - more than 5,000 craftsmen alone, retinues, maids, will there be no point? A few thousand people are enough to form a small society, enough for Princess Wencheng to live on her own feet!
Of course, these people would not all be around Princess Wencheng. Their main body is a craftsman, and they go to Tufan to teach advanced culture and technology. So when they come, they will definitely integrate into the local area, and use their technology, the grain and vegetable seeds they bring, and the medicine they bring to provide development impetus for local production and life.
So, what kind of existence will Princess Wencheng, who brought them to Tufan, be in the minds of the locals? The answer is self-evident.
What is the love between Princess Wencheng and Songtsen Gampo? There are no records in the historical record. Originally, this was a political marriage, and it was more difficult to produce love than ordinary blind marriages. But Princess Wencheng's entry into Tibet was not only a political event, but also an important cultural event. It is undeniable that she has had a huge cultural impact on the Tufan region.
Therefore, even if Songtsen Gampo dies, Princess Wencheng can continue to enjoy people's love in Tufan as a cultural emissary from afar. Husband? child? Alas, before Songtsen Gampo died, do you think she ever had?
Whether voluntarily or by force, she had given up the normal family enjoyment of a woman for the sake of national friendship. She "carried the weight forward" for the sake of the "quiet years" of the Han and Tibetan people, and it was impossible to take into account her personal happiness.
She will continue to live in Tufan and continue to spread culture and technology.
At least it is better than going back to data and being an ordinary aristocratic widow.
