A person with red nail polish is studying Chinese

A person with red nail polish is studying Chinese. The person's left hand is holding the book open while their right hand is resting on the page. The person is highlighting text in pink on the left-hand page. There is also highlighted text in red on the right-hand page. The text on the left-hand page appears to be about grammar and the use of certain prepositions. The text on the right-hand page is mostly illegible. The location based on the coordinates (latitude: 25.669, longitude: 100.155) is in Da Li Bai Zu Zi Zhi Zhou, China. It is not possible to tell what type of environment the person is in from the photo, but it could be indoors.
