We usually capitalize the phrase "New Year"

I have prepared some red envelopes to give to my daughter, nephew, niece, parents and inlaw-on-parents.

Strangely, we don't really say "parents-in-law", at least where I'm from. You can use the word "inlaws" to talk about your mother-in-law and father-in-law.

Your original sentence is perfectly fine. I think my correction is a bit more natural. We don't usually say "more excellent" in my experience, either something is excellent or it's not.

You can also say
- surpass men in every regard
- outshine men

I remember Wwhen I was a child, my parents and some older relatives would give me some money on the eve of the Lunar New Year.

My older sister suggested meto me to save my money together with hers, she said if we saved together it would make usallow us to buy more items.

I would put it simply "My sister suggested we combine our money together. She said that way we would be able to buy more valuable items."

She used our money to buy some popular cassettes she enjoyed at thate time, although I didn't like them.

It is fine to use "that time" here, but it's more natural to use "the time". "At the time" is kind of a common English phrase.

After my older sister started workeding, she also giave me some money in such a moment, she never stint. She was never stingy with her money onwith me.

The last sentence in my correction is a bit awkward I think. I tried to match your intention in the original post. You could also say:
- She was generous with her money on my account
- She never spared any expense for me
But these have slightly different meanings.

Today is a great day for most people from ChinaChinese people.

They are also waiting for a sumptuous meal tonight, which every family is happy to pay for it.

this sounds more natural

Even if they have no money they will probably borrow from others to make a nice meal.

'Sumptuous' is not a common word used in English, I would use 'lavish' instead.

Even if they have no money, they probably borrow some from others to make a nice meal.

In English, you would say 'sister-in-law' for example, but for your partner's parents we would usually say 'in-laws'.

I wasn't quite sure what you wanted to say here as 'stint' is not used like that in English, but I have tried my best to work it out.
