On the whole, fully automatic is definitely good, but now fully automatic jinao is generally not easy to use, because the technology is not very mature, and no one has invested so much money to study this thing. If you have to use it, you should use an imitation manual, but it is better to use an automatic rotating jinao and spread it manually. You can go to Baidu to search for "Yanwen Machinery" and have a look at it, hoping to help you.
