We should drink different kinds of tea all year round. We are sleepy in spring, and drinking some scented tea properly can avoid sleepiness. It's hot in summer, so you should drink some green tea to relieve the heat. You should drink some oolong tea properly in autumn, and you can also drink other teas. In autumn, I don't think it is necessary to drink oolong tea. In winter, I'd better drink some black tea to keep myself warm.

There is no need for the landlord to drink some tea that meets the needs of the whole year, but he can also drink some tea scented tea that he likes: rose tea, red rose tea, jasmine tea and so on.

And green tea: Longjing Biluochun and so on.

I won't explain them to the landlord one by one. The landlord can go to Baidu and search. I don't like to always refer to everything written by hand with letters or abbreviations. The landlord can check that I didn't copy them. Thank you!
