[PyQt] how to dynamically add label to pyqt window

[Joongi]

I need to be able to dynamically add an object like a label to my window. How do I do that? Here is the code that I have.

import random
import sys

from PIL import Image
from PyQt5 import QtCore, QtWidgets
from PyQt5.QtGui import QPixmap
from PyQt5.QtWidgets import QApplication, QWidget
from Image2 import Ui_Form


class MyMainWindow(QWidget, Ui_Form):

    human_list = []

    def __init__(self, parent=None):
        super(MyMainWindow, self).__init__(parent)
        self.setupUi(self)
        self.addHuman(random.randint(1, 10000), random.randint(1, 500), random.randint(1, 200))

    def mouseDoubleClickEvent(self, event):
        self.addHuman(random.randint(1, 10000), random.randint(1, 500), random.randint(1, 200))

    def addHuman(self, humanId, x, y):
        human = HumanLabel(humanId, x, y, self)
        human.addHumanLabel()
        self.human_list.append(human)
        QApplication.processEvents()



class HumanLabel():

    def __init__(self, humanId, x, y, Form):
        self.humanId = humanId
        self.x = x
        self.y = y
        self.form = Form

    def addHumanLabel(self):
        self.label = QtWidgets.QLabel(self.form)
        self.label.setGeometry(QtCore.QRect(self.x, self.y, 500, 375))
        img = Image.open('./321.jpg')
        img.resize((20, 20), Image.ANTIALIAS)
        self.label.setPixmap(QPixmap('./456.jpg'))
        self.label.setObjectName(str(self.humanId))


if __name__ == '__main__':
    app = QApplication(sys.argv)
    win = MyMainWindow()
    win.show()
    sys.exit(app.exec_())

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtGui import QPixmap


class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(500, 375)
        self.label = QtWidgets.QLabel(Form)
        self.label.setGeometry(QtCore.QRect(0, 0, 500, 375))
        self.label.setPixmap(QPixmap('./123.jpg'))
        self.label.setObjectName("background")

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))

The problem is when I double click the mouse that the new human label is being created but it will not show on the window. How do I get the label to show on the window?
