There is an adult primary school downstairs in the old neighborhood committee of An Lan community. From grade one to grade six, there are three classes a week, all in the evening, and the two semesters are the same as those of students at school every year. It's a holiday now, and classes will start on September 10 in the second half of the year. At that time, your mother can sign up. Most of them are middle-aged women who have never been to school before, and now they all start with Pinyin. If you can't find the address, leave me a message and I'll ask for your phone number another day.
