There is no Chp 7,8 in data 

I am a chinese buyer of the book “Data Wrangling with Python". 
When I read for the chapter 7, I found I could not find the data in the https://github.com/jackiekazil/data-wrangling/tree/master/data.
There is no Chp7 & Chp8. Could you help to upload the file to all bookers or send the file to me?
That's really helpful.
