To tell you responsibly, I didn't know which was better before. You must go to Yin 'an this year. I swear on my personality that you will never regret it! This year, Yinan has been transformed. Four leading teachers from No.1 Middle School undertake Yin 'an Tutoring School. They are Shi Jiabang, Ding Huaimin, Guo Fei and Kun Wang, and their teachers are absolutely first-class in northern Anhui!
