Why don't Jews take off their little hats?

The Jewish dome cap is called "kipa" in Hebrew, which means "covering" and means to show the fear of God. One day, you can't be "bald", you should separate them with a hat. At first, however, Jews didn't wear a round hat, let alone use it as their symbol. Ancient Jews were nomadic tribes in the two river basins. When they fled persecution and trudged westward to Canaan on the Mediterranean coast, they still kept the costumes and customs of nomadic people. At that time, they were wearing linen robes or leather clothes, plus wool or linen, cotton and leather clothes, which were dark brown or with white stripes, which could protect them from wind, sun and rain during the day and keep out the cold at night. They wear belts, headscarves and no hats when they go out. Women wear veils and jewels. These customs are very similar to those of later Arabs. After the Hebrews came to Canaan, they founded Judaism and established the Kingdom of David. Later, Jews who fled to Europe were discriminated against and were not allowed to wear headscarves. Besides, wearing a headscarf is really inconvenient. They were forced to wear hats as an insult. However, Jews have a strong national cohesion, and they gradually assimilated these foreign hats into their national costumes, which have religious implications and evolved into the current round hats in the Middle Ages. Jews dress casually and neatly, don't like to wear ties, and like to wear cool sandals in autumn and winter. The way they wear small round hats, to be precise, should be called tops, because it is too small and light, slightly larger than a fist, lightly buckled on the top of the head, and pinned to the top of the head with a clip for women's hair. Bald people have to transfer the edges of some hair. The darker the Israeli round hats are, the more pious they are, so most of them are black and blue, and there are fewer white ones. Materials are usually cloth and velvet, but there are also yarn-dyed and plaid. Prices also vary from a few shekels (4 shekels $ 1) to several hundred shekels. Small round hats can be bought everywhere in Israel. In wailing wall, synagogues and other places with solemn religious atmosphere, there must be a box of small hats for tourists to wear for free. Most of the round hats provided here are black, cut into circles or squares with forest paper or kraft paper. Tourists just need to buckle it on their heads and hold it down with their hands, even if they are devout about where they are going. Today, there are about 200,000 members of extremist Jewish sects in Israel. Many of them wear thick black felt hats or black fur hats and long black coats all year round, and even in hot summer, they are tightly covered. Their children are dressed in this way, only wearing a small round hat. At present, most secular Jews in Israel, especially young people, don't wear hats at ordinary times. They are all small round hats, and there are usually several. When they go to the synagogue, they still wear hats and headscarves to show their respect for God and their ancestors. When many Jews are abroad, in order to prevent terrorist attacks, they no longer wear small round hats, and even say that they are Jews, so as not to get into trouble.
