What are the seven horcruxes of Harry Potter?

The seven horcruxes in Harry Potter are: the diary of Tom Riddle, the ring of Marvolo Gunter, the small gold box of Slytherin, the Holy Grail of Hufflepuff, Ravenclaw's lost crown, Nagini and Harry Potter.

Voldemort's soul was split seven times, eight soul fragments, six horcruxes, one on Harry and one on Voldemort himself.

When Voldemort killed Harry, Abada's death curse bounced back under the protection of his blood relatives. His soul fragments were broken into two pieces, one attached to Harry's body, and the other remained in the body, which was later used for rebirth.

Because Voldemort sucked Harry's blood when he was resurrected, the protection of blood relatives (sacrificial curse) still exists and has not been destroyed (that is, Harry himself is not dead), but Voldemort's soul fragments in his body have been destroyed.

The method of making horcruxes:

If you want to make horcruxes, you must first split dark wizard's soul. Dark wizard split his soul through murder and other evil things. By using a special spell, the soul will be separated and transferred to that object to make a horcrux. Let's be clear here. Voldemort did split his soul through meaningful and intentional murder, but it doesn't mean that dark wizard split his soul once after a murder.

Because murder is a common occurrence in dark wizard. So in theory, as long as dark wizard mastered the method of making horcruxes, he could make many horcruxes like Voldemort. But Dumbledore said that no wizard except Voldemort can split his body into more than two parts and create more than one horcrux.

So it's not just murder. It depends on whether the way to kill people is evil or cruel, and whether dark wizard's soul is evil. It can be seen that it is not just a simple murder, but the conditions are very harsh. Maybe only Voldemort can make more than one horcrux.
