This answer comes from the understanding of the geographical location of Xinxian county and the observation and speculation of the surrounding terrain of the college.

Xinxian County is located in the south-central part of Shanxi Province, with relatively flat terrain and low altitude. The place where the college is located is also within the urban area, and the surrounding buildings are mostly low-rise buildings, with no obvious highlands or peaks. So it can be inferred that the altitude of the college should be about 300 meters.

The practical solution to this problem can be confirmed by asking local authorities or using map surveying tools. If relevant measurement or planning is needed in practical work, professional measuring instruments can be considered for accurate measurement.

It should be noted that altitude is a relative concept, and there may be different calculation methods and standards in different places and occasions. Therefore, it needs to be adjusted and applied according to the specific situation in practical application.
