Xiezhai is a level 12 Persona of the Temperance Arcana, and actually the second one for that Arcana (Asparas is level 3). There's a few ways to go about getting one, with fusion being the first and obvious option. To do that, you will need to be level 12 with your protagonist, which is possible in the early parts of the second labyrinth or if you grinded enough in the first.
You can easily do a Normal Fusion with a Persona you can get after battles in You in Wonderland (Empusa) with one of the starting Personas you got (Sandman). Alternatively, it's possible to get one after a battle in Group Date Cafe, but it's probably easiest to do the fusion above.
