Sinophobia is when people are afraid of or have negative opinions or attitudes about Chinese or Chinese culture. Some people may have these opinions and attitudes because of a lack of understanding or knowledge. These people may hear a lot of negative things about Chinese or Chinese culture and come to believe them without further investigation. Other people may have these opinions because of something bad that has happened to them in the past, such as discrimination or unfair treatment. People with sinophobia may act in mean or hurtful ways towards people from China.
