What do you mean by "wholeheartedly for everyone, wholeheartedly for everyone, wholeheartedly for everyone"?

Landlord, I guess what you want to ask is: unite as one, unite as one, be deeply rooted in people's hearts and be relaxed and happy. What do these four words mean? United as one: ten million people are United as one. Describe unity. Up and down with one heart: up and down with one heart. Deeply rooted in people's hearts: it means that ideas, theories, doctrines and opinions are deeply understood and supported by all people. Feel relaxed and happy: open-minded and cheerful.
