Let's start with the pipa. Since you are a college student, you are an adult. It is not expensive for an ordinary adult to practice pipa. If you want to save money, you can even buy it second-hand. In fact, the more popular musical instruments are, the more spiritual they are. For a treasure, a novice can even get a pipa at around 500, and a better one can set the budget at around 1000, and there is not much quality problem after using it for a long time. And the small cost of nails is not counted.

Secondly, again, it depends on what level you want to learn. If you are just self-sufficient, there are many free tutorials online, most of which can meet the demand. But if you want to find a teacher, it probably doesn't belong to the category of work-study program. Gear hobbing machine has always been a pastime after solving the problem of food and clothing. 10 years ago, the price of a class (45 minutes /60 minutes) was about 100 RMB. Anyway, it's cheaper than the piano, and a famous teacher will be more expensive. Moreover, most of them are young, and adults generally don't accept famous teachers very much, so they don't mention them in their bones, and their temper is basically fixed. For example, the teacher we followed since childhood not only coached the piano, but also taught character, so it is very important to follow the teacher. However, nowadays, young teachers in the General Conservatory of Music will still reap young people. If you really want to learn, you can go to them.
