Is there anything that is not illegal in ancient times, but is illegal in modern times?

Different times have different constraints on people, so there are actually many things that can be done in ancient times and broken in modern times. But I think the first thing that most people think of is the disappearance of polygamy. In ancient times, the idea of son preference was very serious, and the whole social atmosphere was that men were superior to women. Therefore, polygamy is practiced, even by state rulers, and there is even a saying that "there are three thousand beautiful women in the harem", and so are the people. The rich and powerful men in the family are basically three wives and four concubines. But in modern times, if you dare to be polygamous, it is bigamy and illegal. Even if the country doesn't know, your wife will break your leg!

There is also about whoring. In ancient times, brothels were legal. After all, according to the data, brothels have to pay taxes to the government, and they are also very heavy taxes, which makes brothels almost an important source of revenue and expenditure for the government. Think of a brothel woman standing in the street to attract guests in a TV series. If they break the law, they dare not do so. But now, what the country mentions every day is to crack down on pornography and gambling! Don't talk about whoring, someone will set up a yellow website and it will fly all over the sky! Therefore, in modern times, whoring is definitely not allowed!

Finally, a funny one is to shoot tigers! Actually, it's wrong to kill tigers, but it's illegal hunting. In Water Margin, it is written that Song Wu killed a tiger. Song Wu hit the tiger with his bare hands after drinking, and he also hit the tiger, which was very powerful. But today, I dare not shoot tigers. After all, tigers are national protected animals. If you kill a tiger, it's illegal hunting. If you don't kill the tiger, you will kill the tiger. This is cruelty to animals!
