The war of public opinion is very important. Taiwan has always said that the mainland can't afford eggs, lives in thatched houses, and has poor security. In fact, I live in Xuzhou, where the security is very good, and I even add 2 eggs to my rice noodles. Most Taiwanese people believe it, just like how people believed that laundry detergent could be used as white powder during the U.S. invasion of Iraq. Most people are unable to know the truth, just like everyone is promoting that altcoins are worthless.
