Today is the Great Heathottest day of the year according to the 24 solar terms.

Right?

It's true.

You can include this in the next sentence, but "It's true." cant be a sentence

Even yYesterday, which was the day before the Great Heat, when I cleared my coffee cup at night, which and it felt moldy. By the way, his is the same cup I had used in the morning, that cup felt moldy.!

this is like the smoothest way to say it lol. i think youre using mandarin grammar for your english so be careful. in english we kinda take a while to get to point.

Even though it's one of the most unbearable days for Chinese people, thof the year, Chinese culture still givvalues it compliments, because it's also the time when crops grow the fastest.

AndHowever, different regions have different ways of celebrating it.

I need to learn this type of positive attitudee positivity that comes from the traditional Chinese culture.

I should calm myself down and focus on the growing plants since I've tried my best oin my garden with little windowsill garden.
