Who is a forever healthy comrade?

Lin Biao. In China in 1960s and 1970s, no one was more charming than Chairman Mao. However, at that time, many newspapers and non-governmental organizations wrote in large letters not only in the text, but also in the abstract: "Long live Chairman Mao!" "May Comrade Lin Biao be healthy forever!" So Lin Biao got the title of forever healthy comrade.
