Huai Su's Autobiography, scribed in 776 AD by Buddhist monk Huai Su (725–785 AD), is considered one of the finest cursive script works in Chinese history. The original is lost, but three modelling copies existed; the Shu version is deemed superior to the Su version held at the National Palace Museum in Taipei for its artistic variability and consistency with Huai Su's style. Huai Su's cursive script tradition traces back to Han Dynasty calligraphers and was influenced by his discourse with Yan Zhenqing.
China restricts geographic information to authorized entities under state control, prohibiting private surveying and mapping since 2002. The restrictions, justified as protecting state security, result in fines up to 500,000 CNY, disabled GPS features on cameras, and misaligned maps, while critics argue they protect state monopolies and enable political repression.
