Do things by experience and laugh at others.

There are two points. One is that it is still an era of technological innovation. Technology is not so developed, and it is not simply and quickly applied to all aspects. It still needs a large number of professionals to develop and gradually broaden its applications. The initial investment is large, but the output is not timely.

On the other hand, according to people's experience, it can be applied and adapted quickly for production and profit. Moreover, the replication of this kind of experience, although not as easy to popularize as technology, can be replicated quickly among a few people relatively without conceptualization, theorization and digitization. In this way, when the demand reappears, the first choice is still experience, not technology.

Of course, this is especially true in China. From modern times to the present, China people are more sensitive to language and human feelings. In this way, experience can be easily replicated in China. China's efficiency, wisdom and mobility are still relatively high, which means that China will have more experience. Of course, this shortcoming is that experience is relatively easy to use, but with rapid development, it is not suitable for such a problem as slow development of mechanical technology in the early stage and insufficient timeliness, and it is not suitable for the production and living environment at that time, so there will be a problem of relatively slow technology.
