When will Tianjin harvest cabbage and radish?

I want to ask when Tianjin will harvest cabbage and radish. In Tianjin, cabbage and radish are harvested in 1 1 month, and the growth period of cabbage and radish is generally 3-4 months. The ripening time of Chinese cabbage and radish in different regions is different, usually in the last month of autumn. In the northern areas of Tianjin and Beijing, Chinese cabbage and radish are harvested in 1 1 month. So Tianjin harvested cabbage and radish in 1 1 month.
