Go to the library or bookstore and look in the self help or sociology or health or food section and find a book about budgeting or lifestyles or mental health or cooking, whatever interests you.

One works at a job to earn money to buy food, shelter, and clothing, then other things. Your mother only gives you an allowance but you could make a mini-world with it, practice going out and buying food at restaurants and shops and talking to proprietors and staff, you could learn to cook simple meals to feed yourself or help your mother, you could start a savings plan, only spend 200 yuan a month, save 100 for something bigger; learn to invest it if money management interests you, make yourself some money or start a business of some type or use it to help others. You could learn to make or care for clothes, work with textiles. You could investigate housing.

I love thinking about the top three things everyone needs; food, shelter, clothing and seeing how many different things in those three "needs" there are to explore.
