Language is powerful in China. Wars were fought in China to unify culture. For example, the Chinese language in modern vernacular is generally not referred as a language in itself but referred as zhongwen, or "Chinese culture." The first emperor to unify China realized how important for maintaining power it was to have the people using a single common language (just as it were with the Roman Empire, compared to after its fall). The Qin dynasty despite its short reign laid the cultural foundations for generations of China (including and up to now). Before that, China was a collection of several warring states with their own written languages that the Qin dynasty immediately abolished. It allowed them to centralize administration of standards and take power from local lords to the central bureaucracy. What is happening in Hong Kong is a power play by the mainland authorities, just as it was in many instances in mainland history starting from the first emperor. My mother's family was from southern China, and relocated to Taiwan when the Communists won, my maternal grandparents' family having worked in the Kuomintang government. While my grandparents' native tongue was Cantonese, the only language my mother knows from her years in Taiwan is Mandarin (the Taiwan authorities had a strict prohibition on non-mandarin Chinese dialects).
