下面发表的是,关向应1924年冬赴苏学习之前,从上海给其叔父关成玉、关成顺的一封信(全文)。这封信对研究关向应同志参加革命早期的政治思想状况有重要价值。原信是以“上海闸北市民协会公用笺”,用毛笔所写(原件已报送中央档案馆)。文中有个别错字,我们用()号字加以更正,标点符号基本未动,供读者研究参考。 What follows is a letter from Shanghai to his uncle, Kuan Cheng-yu, Guan Cheng-shun, before the winter of 1924 to learn from the Soviet Union (full text). This letter is of great value to the study of the importance of taking part in the state of political thought in the early days of the revolution. The original letter is based on “Shanghai Zhabei Association of Public Note”, written with a brush (the original has been submitted to the Central Archives). There are some typos in the text, we use () number to be corrected, the basic punctuation did not move, for readers to study for reference.
