I want to find a nursing home with better medical care and environment for my grandfather in his eighties in Changchun.

You'd better choose the public one. Public government subsidies, private ones are all for profit, which is also good for the elderly.

After all, the old man found another home for the old man in the nursing home, just like the child entered the long-term care center. You should often visit the old man when he sends an email. Old people's hearts will be empty, and filial piety should be the first, so we should set an example for the next generation.

Let the old man know that the purpose of sending him to the nursing home is to find a place more suitable for him, where there are old people who can talk like him, rather than sending him away like a burden.
