How would it be more appropriate to depart from Jiuzhaigou to Zoige for a day at around 5:00 p.m. on August 12?

Depart from Jiuzhaigou at around 5:00 pm on August 12, and drive to Ruoergai by self-drive. I plan to stay in Heishui on the evening of the 13th. I would like to ask where I should stay on the night of the 12th. How can I go to Ruoergai on the 13th? What attractions can I visit, thank you
