Astronomical problems; Are some constellations only visible in the northern hemisphere and some constellations only visible in the southern hemisphere?

You can see the all-sky constellation on the equator. The North Pole can only see the constellation north of the celestial equator, and the South Pole can only see the constellation south of the celestial equator. In the northern hemisphere, the higher the latitude, the fewer constellations south of the celestial equator and the shorter the time (all constellations north of the celestial equator can be seen). In the constellation north of the celestial equator, the more you can see the constellation at night, you don't need to set it during the day. In the southern hemisphere, the higher the latitude, the fewer constellations north of the celestial equator and the shorter the time (all constellations south of the celestial equator can be seen). In the constellation south of the celestial equator, the more you can see the constellation at night, you don't need to set it during the day.
