I feel that English grammar is particularly troublesome. What are the British doing this for? Is it just to make it hard for Chinese people to learn it?

For Westerners, Chinese grammar is more complicated and the pronunciation is more perverted. There is no concept of four tones in English, which is hard enough for foreigners to get past. Pronunciations such as [e] [ai] [u] [u:] in English are also not specifically reflected in Chinese characters, and Chinese people are baffled.

English and Chinese are not the same language family, and there is a big gap, so it's a bit difficult to learn.

As far as grammar is concerned, Chinese tenses are reflected in: being, already, (eaten), had, later ...... and so on, which is much more complicated compared to English. The language doesn't need to know why, because that's how it's said, just learn and memorize more. Foreigners didn't make it difficult for you on purpose. Chinese is more complex than English, foreigners are not hate us?
