I am a graduate of Xi 'an University of Science and Technology majoring in geological engineering. The museum is located on the left-hand side of the entrance on the first floor of the library in Lintong campus, but it is not open to the public. However, sometimes it can be organized by public institutions and approved by school leaders. Students of other majors may not visit until their freshman year. If there is an internship, we will often enter it. Mainly used in mineral rocks.
