参考这里：

1. #figure(bgcolor=None)
   
2. ax = axesm(axison=False, frameon=False)
   
3. geoshow('cn_province', edgecolor='k', facecolor='c', size=0.1)
   
4. 
   
5. #Add scale bar
   
6. ax.scale_bar(0.2, 0.22, width=200, linewidth=1, fontsize=14, \
   
7.     bartype='scale_line_1')
   
8. 
   
9. #Add north arrow
   
10. ax.north_arrow(0.3, 0.9, width=40, height=40, linewidth=1)
    
11. 
    
12. #Set extent
    
13. xlim(70, 140)
    
14. ylim(15, 55)
    
15. xticks(arange(-180, 181, 30))
    
16. yticks(arange(-90, 91, 30))
    
17. title('Scale bar & north arrow')
