Japanese private school instructors recommend everyone to join the teacher. Are there any rewards?

Japanese private school tutors suggested that everyone should pay their teachers. Japanese private schools, private specialized educational places developed during the Edo period in Japan. Private schools appeared in Nara era, which once developed in Heian period and gradually declined after Kamakura shogunate. During the Edo period, academics flourished, and scholars came forth in large numbers in hundred schools of thought. Scholars from various schools competed to establish portals and train disciples, and private schools developed accordingly. Most of the setters are folk scholars, and some are Confucian scholars who teach in shogunate schools or vassal schools. They use their homes to impart knowledge, and most of them are teachers, most of them are Zhu scholars, and there are also some Yangming scholars, ancient scholars and China scholars. At the end of the shogunate, there were still orchid scholars who set up private schools to study orchids. The teaching content is not uniform, which is higher than that of temples and rural schools and equivalent to the level of secondary professional education. Some later developed into private specialized schools, such as Keio University.
