I am comfortably greeted by the scene of your video with a film as warmhearted and unequivocal and undemanding and unquestioning as a eulogy,
because such scene never exists in China in winter.
My English is very limited but I am boldly or coldly to empress by "stealing" something that is connected with my poor English.
So inevitably lot of errors must be full of my English ,which, I hope, will be corrected by native English speakers.
Question: Are all of the sentences above grammatically correct?
Could you help correct those sentences grammatically incorrect?

Answer

I am comfortably greeted by the scenes in your video, which is as warmhearted, unequivocal, undemanding and unquestioning as a eulogy because such a scene never exists in China in winter.

My English is very limited but I am boldly trying to improve it by "stealing" something that is related to my poor English. So inevitably my English must be full of a lot of errors, which I hope will be corrected by native English speakers.

Answer

Watching your video comforts me so. It warms my heart. [Or, it is "heart warming"].
[I don't understand what is unequivocal? What is unquestioning?]
[People are warmhearted. It is not wrong to say a film is warmhearted, but really it is the person who made it who is "warmhearted", not the film itself].

I don't understand the sentence that starts with "My English".  "Empress" is not a verb.  "Coldly" is not used in this way.

My English is inevitably filled with errors, whose correction by native speakers I do (or "will") welcome with gratitude.
