How to plot multiple chart on one figure and combine with another?

Question

# Create an axes object 
axes = plt.gca()

# pass the axes object to plot function
df.plot(kind='line', x='鄉鎮別', y='男', ax=axes,figsize=(10,8));
df.plot(kind='line', x='鄉鎮別', y='女', ax=axes,figsize=(10,8));
df.plot(kind='line', x='鄉鎮別', y='合計(男+女)', ax=axes,figsize=(10,8),title='hihii',
        xlabel='鄉鎮別',ylabel='人數') 

It's my data.

This my output df.plot

First question is how to display Chinese?

Second is can I use without df.plot to plot line chart?

last question is : There are four graphs(use subplot): the line graphs of male and female population and total population(男、女、合計(男+女)) in each township; the line graphs of in-migration and out-migration(遷入和遷出); the long bar graphs of household number(戶數); and the line graphs of births and deaths(出生和死亡).
