1. Tibetan Buddhism emphasizes tantric practice, including various rituals, initiation and continuous practice, while Han Buddhism also contains tantric elements, but its tantric inheritance is not as profound and extensive as Tibetan Buddhism.

2. There are many sects of Tibetan Buddhism, such as Ningma Sect, Kadang Sect, Sakya Sect, Gelug Sect, and each sect has its own unique teachings and practice methods. In contrast, the sects of Han Buddhism are mainly pure land Sect and Zen Sect, and their teachings and practice methods are different from those of Tibetan Buddhism.
