Qi Baishi's masterpiece "Song and Li Tu Si Yan Lian" is the largest painting and calligraphy that Qi Baishi has seen in public and private places over the years. This painting is 266 cm in vertical direction and 100 cm in horizontal direction. The couplets of seal script "Long life, peaceful world" are 264.5 cm in vertical length and 65.8 cm in horizontal length. The picture is magnificent, and there is a metaphor that pines and cypresses surround Britain. The four-character couplets matched with seal script are rich and natural, dignified and elegant, with excellent meaning: "Life is better than Nanshan, and the world is peaceful", which can be called the unique spiritual product of Qi Baishi's paintings and calligraphy. In this picture, the protagonist is a goshawk standing on a pine branch, proudly independent. The main feather and the tail feather are pointed out with thick ink and Jiao Mo's broad pen, with distinct layers, powerful wings folded and powerful claws clinging to the trunk. Jiao Mo drew an eagle's beak, which attracted people's attention, while the goshawk was angry and full of sparks. The eagle stood on its side with its head slightly twisted and full of energy. It looks at the vast land and moves silently, highlighting the sense of power of the image. By comparing the small note of "the horizontal points on the paws are extremely dense" in Baishi's paintings, we can see the realistic source of Qi Baishi's careful observation of life and portrayal of image details. Draw a pine tree and a cypress tree in the picture. Pine trees are in front, depicted in light ink, branches are upright and inclined to the right, and then inserted obliquely from the top, and pine needles are written in thick ink, which shows the pen power; The cypress tree is behind, the ink color is thicker and the posture is more awkward. "Pine and cypress" coincides with a long life, but the unique style in the frame has already jumped out of the exact function of "celebrating life", but with the metaphor of "lasting success", it has become an expectation of a dying beautiful vision after the war. Song Ying is one of Qi Baishi's favorite paintings and is familiar to the audience. "Eagle" means "hero", vigorous and powerful, and "pine and cypress" means longevity.
