Sun Chuanfang
The third Communist uprising in Shanghai took place from 20–21 March. 600,000 rioting workers cut power and telephone lines and seized the city's post office, police headquarters, and railway stations, often after heavy fighting. During this uprising, the insurrectionists were under strict orders not to harm foreigners, which they obeyed. The forces of Sun Chuanfang withdrew and the uprising was successful, despite the small number of armed forces available. The first Nationalist troops entered the city the next day.
