Hi, is there any sleeping bus from Gongbei long distance bus terminal to Zhangjiajie?

There is no long-distance bus from Gongbei to Zhangjiajie. If you want to take bus, you need to go to Shangchong Bus Station, where you can find only one bus for Zhajiajie at around 09:00 in the morning. The bus cost around 16 to 17hours. The fare is around 240RMB.
It is suggested to reach Guangzhou and then take flight to reach Zhangjiajie directly.

Thanks so much for your reply.
Best regards.
