Today, pure Classical Chinese is occasionally used in formal or ceremonial occasions. The "National Anthem of the Republic of China" (中華民國國歌), for example, is in Classical Chinese. Buddhist texts, or sutras, are still preserved in Classical Chinese from the time they were composed or translated from Sanskrit sources. In practice there is a socially accepted continuum between vernacular Chinese and Classical Chinese. For example, most official notices and formal letters are written with a number of stock Classical Chinese expressions (e.g. salutation, closing). Personal letters, on the other hand, are mostly written in vernacular, but with some Classical phrases, depending on the subject matter, the writer's level of education, etc. With the exception of professional scholars and enthusiasts, most people today cannot write in full Classical Chinese with ease.
