What's the difference between fascist symbols and China's swastika?

The swastika used by the Nazis can be divided into positive and negative characters. It is generally believed that the symbol of Nazi is negative swastika, but China's swastika originated from Buddhism. There is no special distinction between positive and negative characters, and both can be used. In the secular world, it means good luck and longevity, but after World War II, people generally used the cross sign used by the Nazi Party to distinguish it from the Nazis. Another difference is that the swastika of the Nazi symbol rotates 45, while the swastika used by China is usually upright.
