Is the salary of teachers in Changshu much lower than that in Kunshan?

A lot. After inquiring about the teacher recruitment brochures in Changshu and Kunshan, we know that the salary of teachers in Changshu is 4,000 yuan per month, while that in Kunshan is 7,000 yuan per month. So I know that the salary of teachers in Changshu is 3000 months lower than that in Kunshan, which is much lower. Changshu city, referred to as Yu for short, is named "Changshu" because of "fertile land and no floods and droughts at the age of", and it is a national historical and cultural city.
