Lang Shining painting and calligraphy signature seal

It's far from Lang Shining. Lang Shining's handwriting on his autograph is particularly beautiful, and his painting method is almost meticulous in Lang Shining's meticulous painting. Here, including the later famous Xinyu Pu, there is the shadow of Lang Shining. I saw a corner of this painting, and it was freehand brushwork. These strokes are very poor. Besides, not all Lang Shining's signatures have a courtier.
