1. Stealing 800 kilograms of copper, worth about 1 10,000 yuan, belongs to the standard of "large amount" in theft. The punishment according to law is: fixed-term imprisonment of not more than three years, criminal detention or public surveillance, and a fine or only a fine.

2. When a gang commits a crime, it will distinguish between the principal and the accessory. According to the amount, the penalty is not the amount of the share, but the amount involved. An accessory shall be given a lighter punishment by analogy with the principal offender.

3. Different provinces and cities have different sentencing standards for theft. Please refer to the criteria of the crime location again.
