Hello everyone, I am Grandpa Amu, an old carpenter who likes to focus on woodworking. If you like my videos, please continue to follow my channel. The videos we shoot are mainly wooden crafts. Next, my son and I are also working hard to shoot more creative videos and share them with everyone, so that every reader can learn knowledge and relieve their mood. There are also many wonderful works in the channel, and everyone can enjoy them slowly. Thank you for your support.
