China first invented the compass, but why did westerners first travel around the world?

Lu Xun said in The Advantages and Disadvantages of Electricity:

During the Japanese shogunate, Christians were massacred, and the punishment was very fierce, but it was not allowed to be published. In recent years, many documents were published at that time. I have read "The Martyrdom of Red Sun Zhidan", which records the torture of Christians, or take them to the hot springs and water them with hot soup; Or make a fire around and bake it slowly. This was originally a "stake", but the person in charge removed the fire and changed the death penalty into a crime of abuse.

China is even more cruel. The Tang people said that there was a record in the Ministry that a county magistrate tortured a prisoner, roasted him with a torch, and gave him vinegar when he was thirsty. This is a further way than Japan. Now Guanting tortures the suspect, which seems to be a method left over from the Tang Dynasty to fill the nostrils with Chili sauce, or a hero of ancient and modern times, and all roads lead to the same goal.

I once saw a letter from a young man who was imprisoned in a reflection house. The letter said that he had been punished like this before, and the spicy juice had flowed into his lungs and heart, which had become an incurable disease. Even if he was released, he would inevitably die.

This man is a military school student and doesn't know the internal organs structure. In fact, he can turn his nose upside down and flow from the trachea into the lungs, causing fatal diseases, but he can't enter the heart. At about that time, because I was very painful and confused, I suspected that I had reached my heart. But now the so-called torture devices made by civilized people are cruel and surpass this method. There is electrocution in Shanghai. As soon as I got up, I felt a splitting pain all over, then I fainted, and I woke up and was tortured again. I heard that there are people who have suffered seven or eight times in a row, but they narrowly escaped death. After that, their teeth shook and their nerves became dull and unable to recover.

Edison was commemorated the year before last. Many people praised the benefits of telegraph and telephone, but I didn't expect that some people were hurt so much because of the same electricity. The rich use electricity to cure diseases and beauty, while the oppressed suffer and die.

Foreign countries use gunpowder as bullets to defend the enemy, but China uses it as firecrackers to worship the gods; Foreign countries use a compass to sail, but China uses it to see Feng Shui; Foreign countries use opium to cure diseases, while China uses opium as food. The same thing, but that's the difference between Chinese and foreign usage. The lid is not just electric.
