2. Follow the python codes below:
   import numpy as np
   import matplotlib.pyplot as plt
   from matplotlib import rcParams
   from matplotlib.font_manager import FontProperties
   rcParams['axes.unicode_minus']=False
   myfont_kai=FontProperties(fname='/usr/share/fonts/truetype/bkai00mp.ttf', size=15)
   myfont_ming=FontProperties(fname='/usr/share/fonts/truetype/arphic-bsmi00lp/bsmi00lp.ttf',size=12)
   x=np.linspace(0,2*np.pi,100)
   plt.plot(x,x)
   plt.title("準則", fontproperties=myfont_kai)
   plt.ylabel("隸屬度", fontproperties=myfont_ming)
