I understand students' feelings for the old teacher. But learning is your own business. Don't compete with the new teacher. Changing teachers does not mean changing. It is the first thing to adapt to the new teaching method of the new teacher and the new management method of the new class teacher as soon as possible. Every teacher has his own advantages and characteristics. It is wise for you to accept and adapt as soon as possible, otherwise you will find that time really waits for no one! !
