Can't do a ClickEvent on a ClickEvent on a ClickEvent, etc..

What I expected to happen was...:
(sorry for my english I'm not english)
I wanted to do a ClickEvent on a ClickEvent on a Clickevent on a tellraw command and plus. Three clickEvent work but more no. This is an exemple of the command :

/tellraw @p [{"text":"Good","color":"green","clickEvent":{"action":"run_command","value":"

/tellraw @p [{\"text\":\"Very Good\",\"color\":\"red\",\"clickEvent\":{\"action\":\"run_command\",\"value\":\"

/tellraw @p [{\\\"text\\\":\\\"Excellent\\\",\\\"color\\\":\\\"yellow\\\",\\\"clickEvent\\\":{\\\"action\\\":\\\"run_command\\\",\\\"value\\\":\\\"

/say Ok stop the tellraw it's too much..

\\\"}}]
\"}}]
"}}]

But I wanted, for my command to add another /tellraw command. I try (\\\\\"text\\\\\") with five ( \ ) but it doesn't work. I try more ( \ ), I try ( ' ) and other thing but it doesn't work.
Strange thing is that ( \\\\\n ) work but not the tellraw command.

What actually happened was...:
Invalid Json, Unterminated string or other bug report.

Steps to Reproduce:
1. Copy and Paste the command
2. Change the line with the /say command with a /tellraw
