There used to be locust trees in the front and back of the old house. Every time this season, you can see locust trees from the window of my bedroom, bursting with fragrance of flowers into the room, that is the breath of spring! Today, my colleague picked a bag of Sophora japonica for me, smelling the familiar scent, as if returning to the old house, recalling my childhood full of interesting things! Decided to make a plate of Sophora japonica cake to retain the fragrance!
