How to practice left hand flexibility and relaxation quickly?

Self-taught wooden guitar, how to practice climbing grid (hand posture)?
My friend, guitar is a hard and hard road. I have been playing the piano for more than six years, three years with my teacher, and three years of going out to communicate and study. It’s very hard. There are also plans to give up many times in the middle. Regarding what you said about climbing the lattice, you can’t be anxious. You have to step by step. There are 24 combinations of climbing the lattice. Practice with them. Start slowly, step by step. Not pursuing fast, only pursuing every sound has been implemented for a long time. You will naturally find that the left and right become more flexible. One thing to remember is patience. Friends, if you really want to achieve something in music, have attainments. It’s important to stick to it. I believe you. You can do that! If you have more questions about guitar, please keep in touch with me. I’d be happy to give you an answer.
