That's right. Education must first have love. Only when there is love can there be a sense of responsibility. With a sense of responsibility, we can focus on education for a long time. Without love, we can only regard education as a "business activity" and thus "do routine work" every day. He doesn't care about any educational theory or teaching technology, and muddle along every day. Don't say that he doesn't know what children like and hate, but that he doesn't care about their illness or family changes. Such people will inevitably delay their studies. The reality is cruel, not to mention kindergarten teachers, many parents are not very quality. It doesn't mean that having children or getting old will naturally become the embodiment of virtue and wisdom. Many things need to be carefully studied with an open mind to qualify. Only those who really love children can do it.
