What's the name of the only human oil painting in Li Shutong?

Portrait of half-naked women, oil painting on canvas,116.5x91cm, art collection of Central Academy of Fine Arts.

Half-naked women appeared in public as early as 1920. At that time, the magazine Aesthetic Education, founded by Li Shutong's proud disciple Wu Mengfei, appeared in its inaugural issue, Semi-naked Female Statue; But it didn't take long for this work to disappear quietly. 1959, when Wu Mengfei wrote an article in the journal of Central American Art Research, he also mentioned this painting, but he didn't know where it was lost. . In the painting, a young woman is half naked, her eyes are slightly closed, and she leans back on a chair covered with soft cloth, and her long black hair is loosely scattered. The picture is so quiet that people can't bear to wake up the sleeping characters. However, the slightly inclined corner of the canvas, several long or short folds and some pigments falling off in the canvas clearly remind people that this is an old painting for quite a few years.
