I havent played building blocks for a long time. Today, my elder sister and younger brother came to my house to play. My younger brother moved out the building blocks I played when I was a child. We built the building blocks together. First of all, we use the large rectangular blocks as the foundation, the square as the center of the house, the triangle as the roof, and the column as the chimney. We carefully place each block and slowly build a castle. Although I used to play when I was a kid, I still have fun with my sister and brother! Have a good time today!
