Step-by-step explanation:
Neo-Confucianism developed during the Tang time period in response to multiple factors: The fall of the Han Dynasty created a need for a new intellectual and philosophical framework. The Tang Dynasty encouraged philosophical innovation and cultural exchange, which allowed for the development of Neo-Confucianism.
Contact with Buddhist and Daoist ideas influenced the development of Neo-Confucianism, leading to a synthesis of these different philosophies. Economic changes during the Tang period also played a role in the development of Neo-Confucianism as it provided a new moral and ethical framework to guide society in the face of commercialization and social transformation.
