Does Eastern Airlines Guiyang Company provide overnight transfer hotels from Changchun to Shanghai?

I changed planes in Shanghai and booked my own free transit hotel, but it seems that official website and the customer service phone can't apply. I booked it in the sales department and wanted the earliest flight the next day. Specifically, you can see China Eastern Airlines official website:

Subject name: Free hotel accommodation for overnight transit passengers.

Product description: Passengers who arrive at any airport in Shanghai Pudong/Hongqiao Airport, Anyang Airport and Kunming Changshui Airport on the designated flight of Shanghai Airlines and transfer to the earliest available flight of MU or FM within 24 hours will have the opportunity to get a hotel stay as long as they purchase overnight transfer products through specific channels. Overnight transit products include full overnight transit air tickets, one-night free hotel accommodation and free shuttle service between the hotel and the airport. Please consult the sales department of China Eastern Airlines or the appointed agent for the hotel catalogue.

The terms of purchase are influenced by variable factors such as airline, cabin, price and hotel room. We will adjust the terms of purchase at any time. Please consult the sales department of China Eastern Airlines in detail or appoint an agent before purchasing.

Consultation and purchase channels are limited to the sales department of China Eastern Airlines or designated agents.
