Song Huizong was in office from 11 to 1125, and he minted and issued six kinds of annual coins, namely, Founding the People's Republic of China, Chongning, Daguan, Zhenghe, Xuanhe, and a national title coin, Shengsong. There are nearly 1 Qian Wen editions of Song Huizong Nianhao Money, including official script, seal script, running script and "thin gold style" created by Huizong. The square hole money he cast is one of the most exquisite coins in China. Therefore, many calligraphers also collect his annual money. Song Huizong personally wrote Qian Wen's "Chongning Tongbao", "Daguan Tongbao" and "Xuanhe Tongbao" with his original "thin gold body". The font is dignified and beautiful, and the brushwork is tall and handsome, which is known as "iron strokes and silver hooks".
