Why doesn't Meteorology write Xintai?

Xintai is not an independent city. According to the weather history website, the National Meteorological Administration has formulated and standardized the labeling. According to the standard, Xintai is not an independent city, but a county-level city belonging to Tai 'an City, Shandong Province, which is marked as "Tai 'an" on the meteorological map. The purpose of this standardized labeling method is to improve the accuracy and comparability of meteorological information and avoid error correction and confusion.
