What do you think of the historic slash-and-burn farming and mountain refining? Is it something that should be vigorously promoted

Not to be vigorously promoted. For traditional agricultural methods such as slash-and-burn farming and mountain refining, a scientific attitude should be taken to recognize and pass on. On the one hand, these traditional agricultural methods are an important part of China's agricultural culture, with historical and cultural value, and should be protected and inherited. On the other hand, these traditional agricultural methods have some limitations, such as low productivity and damage to the environment, so they cannot be vigorously promoted.
