There is always something you can do. If not, send it to me to help you solve it. Sending pictures is also ok.
If you really want the answer, I recommend you to go to the first floor of Sichuan Book Building in Chengdu. Go to the lotus pond at the North Railway Station 100 meters. There are various versions on the first floor. I bought answers there to do my homework.
There are different versions online. Otherwise, you can send me a picture. I will send you the answer as soon as possible.
