Why Is The Temperature Of Liquid Nitrogen Always -196 Degrees

Why is the temperature of liquid nitrogen always -196 degrees? It is known that the melting point of nitrogen is (°C): -209.8 Boiling Point (°C): -195.6 However, after actual measurement, the temperature of liquid nitrogen is always maintained at about -196 degrees Celsius because it is always in boiling state. Please everyone for the younger brother to answer doubts, extremely grateful!

Liquid nitrogen is at a lower boiling point than the boiling point, isn't it supposed to be, or it all turns into gas and the crystals stay in the same state during the conversion process.
