BecausMany people are often busy working and have no desire to cook, many people areso they get used to ordering takeouts, and even relying on takeouts for three meals a day.

The general guideline is to not start a sentence with "Because...". In these cases, usually it's better to rephrase.

There are more and mMore people to ordering takeout, naturally, there are more and leads to more people delivering takeout.

In my experience, "more and more" tends to be overused by non-native speakers, particularly in writing.

Now there are already 2.65 million ridusers inof Meituan.

(It would be reasonable here to introduce Meituan; it's probably a safe bet that an English-speaking audience wouldn't know what this is.)

Since the size is so largeit is widely used, Meituan should make a lot of money, but Wangxing, the founder of Meituan, said that Meituan has been losting money for many years.

"large size" implies physically big (like an elephant).

Many people have expressed doubts adbout this claim, saying it is impossible.

It is understood that the revenue of Meituan reached 65 billion in 2018, whichmaking ist the second to none on the itop Internet platform.

"It is understood" is passive: generally we should aim for active writing. In this case, who is doing the understanding?

It could be "making it the second-to-none Internet platform", but this is very unnatural; "second to none" might be suitable in conversation (e.g. when you're complimenting someone: "The hero's bravery is second to none.").

However, the "takeaway brothers" and the merchants are all sclaidm that they wouldo not make money, and even Meituan said that they have been losing money, so who is lying?

I don't know what "takeaway brothers" refers to.

Who made theis making money?

Better would be: "Where is the money going?"

In fact, although Meituan earneds a lot of money, their expenses are not smallinsignificant.

While "not small" is okay, it more naturally refers to physical size. More precise choices here are "not insignificant" (or "significant"), "not minor", and "not negligible".

Three expenses such asparticular expenses, namely marketing expenses, management expenses and financial expensese, useds up the profits of 13 billion yuan and lostrevenue leading to a 557 million yuan loss.

"profit" implies making money (after expenses), "revenue" is more precise.

Of whichthese expenses, nearly 60% wais spent on marketing, so it is not surprising to see Meituan advertisement everywhere, and there are many other investments, which require spending money everywherebroadly.

In addition to takeout, Meituan has many businesses, such as hotels, online cars, shared bikes and micro-loans, etc., and its early development is bound to need a lot ofsignificant financial support.

In this way, it is true that Meituan madeboth makes money and lostes money.

"made money" is past tense: it implies it no longer makes money (likewise with "lost money").

Meituan is played a “protracted war”, and made profits after losing money firsting the long game, and is making profits after initial losses.

"playing the long game" is a better choice here https://en.wiktionary.org/wiki/long_game. A "protracted war" suggests some kind of enemy.
