How many years do you get for threatening with a knife?

Article 226 Whoever forcibly buys or sells commodities by violence or threat, or forces others to provide services or force others to accept services, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention and shall also, or shall only, be fined. Simple intimidation generally does not constitute a crime, but some acts also constitute a crime, such as: 1. Asking for property when threatening may constitute extortion. Article 274 of the Criminal Law of our country extorts and extorts public or private property, and if the amount is relatively large, it shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance; If the amount is huge or there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years. 2. Article 8 of the Criminal Law Amendment (III) of People's Republic of China (PRC) stipulates that "those who throw false explosive, toxic, radioactive, infectious disease pathogens and other substances, or fabricate terrorist information such as explosion threat, biochemical threat and radiation threat, or knowingly spread the fabricated terrorist information, thus seriously disrupting social order, shall be sentenced to fixed-term imprisonment of not more than five years, criminal detention or public surveillance; Those who cause serious consequences shall be sentenced to fixed-term imprisonment of not less than five years. " In other words, such intimidation is a crime. If convicted, if the circumstances are serious, he will be sentenced for violating the criminal law, but there is no specific provision for intimidation. You can find the relevant terms according to his threat.
