Why was the incident of Bank of China evading 2.367 billion yuan in taxes exposed? Many people only see one side of the story. The exposure of internal events within vested interest groups is not simply about anti-corruption. Back then, Heshen was so corrupt, yet Emperor Qianlong didn't punish him. Was it because Qianlong couldn't see it? No, it's because Heshen was useful. He was given all the dirty work to do. Heshen was the lubricant for the national treasury, the imperial treasury, and the bureaucratic system, and he could even help Qianlong save money. It was just that during this period, Heshen was managing the wealth on his behalf. Later, Emperor Jiaqing reclaimed the wealth his father left for him (by confiscating Heshen's property), which also served to intimidate others and provided a sufficient reason for managing the people's assets in the future.
