According to legend, the sycamore tree is composed of two trees, which cling to each other and never leave each other. It sometimes represents auspiciousness and loyalty, but it also represents farewell, such as "It rains at midnight on the leaves of the phoenix tree, and the sound of the leaves is parting" and "The lonely phoenix tree locks the autumn in the deep courtyard."
In this book, my parents are like this, my sister is like this, and so am I.
Intention: People are like parasol trees, clinging to each other and never leaving.
