This marriage vow seemed to be no different from any other marriage vow of Zhou Dynasty. It has clear conditions and meanings. But in fact, this marriage was special because it stated clearly that only the male side could forfeit and the witness was the Pope!
Even if there are copies of this marriage vow in Palace Li, no one could destroy this marriage vow either because on this piece of paper, the Pope enchanted his powerful seal. The moment anyone destroys this marriage vow, the seal would also be destroyed. This would be a heavy insult to the Pope.
Chen Chang Sheng earlier said that after Xu Shi Ji obtained the marriage vow, he would hide it in somewhere that couldn’t be found. He didn’t say he will rip it into pieces or burn it into ashes. In the several months of time after he came to the capital, Dong Yu General’s Mansion never tried to steal the marriage vow and destroy it because of this reason.
This kind of special marriage vow was easy to identify as real or false.
