What happened to cause chinese communists to undertake the long march in 1933

The correct answer to this open question is the following.

What caused Chinese Communists to undertake the Long March in 1933 was the following. The Chinese Communists led by Mao Zedong retreated in October 1934. China was living the Civil War years in which Communists troops fought the Nationalist army.  The Long March of the Communist Army lasted one year. The Communist army retreated by night and had to suffer many calamities and deaths. So the retreat was what caused the Long March to evade the persecution and pursue of the Nationalist troops.

the reform movements that arose during the antebellum period in america focused on specific issues: temperance, abolishing imprisonment for debt, pacifism, antislavery, abolishing capital punishment, amelioration of prison conditions (with prison's purpose reconceived as rehabilitation rather than punishment), the humane treatment of animals, the humane and just treatment of native americans, the establishment of public institutions for the care of the destitute, orphans, blind, and mentally ill, the establishment of public schools, the abolition of tobacco use, vegetarianism, health reform, homeopathic medicine, woman's rights (including, at first, especially the establishment of a woman's right to own property apart from her husband and her right to sue for divorce), and the amelioration of labor conditions (including higher pay, the right to form unions, the right to strike, and the demand for limits on the number of work hours, and safe working conditions).
