Can Hangzhou plant pitaya after all?

My pitaya was planted by myself last summer. Last winter in Nanjing, the lowest temperature seemed to be -9 degrees. 1 1 entered Alice's largest transparent sorting box for heat preservation in June, and was taken out indoors at the end of March, successfully spending the winter. Generally speaking, the immortals here are cut off from water at the end of June 10, and the seedlings that will not die after drought will enter the sorting box to keep warm. For more than 2 years, it is enough to go through the winter without water directly indoors.
