This is a set of traditional Chinese landscape paintings, consisting of four scrolls depicting the scenery of mountains and rivers in different seasons. The first scroll shows the spring scene with lush green mountains, blooming flowers, and a tranquil river. The second scroll presents the summer landscape with verdant peaks, waterfalls, and dense forests. The third scroll depicts autumn, featuring mountains in warm red and orange hues, and trees with colorful foliage. The fourth scroll illustrates winter, with snow-covered mountains, icy rivers, and a serene, cold atmosphere. The paintings employ meticulous brushwork and rich, harmonious colors to showcase the distinct beauty of each season, reflecting the changing charm of nature.
