What are the main differences between primitive Buddhism and ministerial Buddhism?

The difference between this sect of Buddhism and primitive Buddhism is that this sect not only inherits the "Dharma" and "Dharma" of primitive Buddhism, but also expounds the "Abidharma", which has three parts: Tibetan Scripture, Dharma and Rationalism.

Buddhism from the time when the Buddha died to more than 100 years after his death is called "primitive Buddhism" or "early Buddhism". Among them, some people call the Buddhism of the Buddha and his disciples "fundamental Buddhism". Because real Buddhism appeared in this period, and this real Buddhism became the foundation of the whole Buddhism in later generations. Conceptually, the teaching method of Buddhism is also the source of the spread of Hinayana Sect and Mahayana Buddhism in the three countries (China, Korea and Japan), so we can understand why it is called "fundamental Buddhism". In short, the "Dharma and Dharma" mentioned by the Buddha has become the foundation of Buddhism. During the rainy season of three months in the year of Buddha's death, an editorial meeting (collection) of Buddhist scriptures was held in Wangshe City, the capital of Mojietuo State. The best 500 Arhat monks among Buddhist disciples gathered together to collect the "Dharma" and "Dharma" they were taught by the Buddha. This is the first collection, also known as "Wang Shecheng Collection".
