The Chinese character “弧” is pronounced as “hú”. In English, it can be translated as “arc”. For example, “a circular arc” means “一个圆弧”. The pronunciation “hú” is similar to the English word “who” without the initial “w” sound. You can practice pronouncing it by repeating “hú” several times. It is important to pay attention to the correct tone when pronouncing Chinese characters. ????
