Urgently beg. How to make a simple erhu (stringed instrument)? Materials should come from daily life. The simpler the better.

You must have seen the appearance of erhu, right? Draw a tiger according to a cat.

The drum of erhu can be a round jar, which is about the size of a real erhu drum.

Find another erhu pole, which can be replaced by a metal mop pole abandoned at home.

The chords of erhu can be sawed short with a wooden hammer handle.

I'm going to the musical instrument store to buy strings. They are very cheap. By the way, I'll buy a string girl, which is also available in a musical instrument store. Eighty cents.

Then there is punching. The two holes on the barrel can be inserted into the piano rod, and the two holes on the piano rod can be inserted into the chord. The chord axis should be tapered, and two small holes should be punched on the chord axis for threading the chord. It must be very small, slightly larger than the strings.

And then it's assembled This need not be introduced. Put it on like a cat painting a tiger.

Note that the "golden daughter" in the middle and upper part of the piano rod can be replaced by nylon wire.

That's all. I don't know if I can be satisfied. Waiting to hand in homework.
