This is a youthful memory in the 1990s, on the plains of northwest Shandong, starting from Qili in the north and Tuhai in the east, a past filled with blood, love and hatred. When they were young, they drank blood wine across a bay of Tuhai River flowing eastward and became brothers. In high school, they had a deep love and close friendship, and had been classmates together for three years. A rain of flowers brings infinite youth! The first part of Zhang Ming's memoir novel "Wind, Rain and Red Dust": Past Classmates.
