The sky is big and the earth is big

In 1925, the war in Northeast China had just ended. Fengling Town on the Songhua River was located deep in the white mountains and black waters. It was very complex with seven elements and eight works, three religions and nine people. The Ma family and the Feng family in Fengling Town have been feuding for generations. The old men of both families are running out of time. Mr. Feng wants to marry his foolish son Feng Luzi before he dies. Feng Luzi had a soft spot for Black Grape, the daughter of Mr. Zhou who taught in the town, but Mr. Zhou betrothed Black Grape to Ma Ye's son Ma Wanhai. After graduating from Medical University, Ma Wanhai was forced to join the army. After receiving a letter from Master Ma, he used a trick to escape from Fengtian. Hearing about the feud between the two families, he secretly colluded with the bandit Xiao Beifeng to loot the Feng family, and the Feng family fell. Soon, Master Feng and Master Ma passed away, but Feng Donkey's dementia recovered. It turned out that Donkey had been pretending to be stupid to avoid disaster. Although Ma Wanhai destroyed the Feng family, his wealth was also dissipated. After that, Feng and Ma took in the orphans Ben'er and Qiu'er respectively. Ben'er and Qiu'er have been childhood sweethearts since childhood, which have caused great headaches for enemies, Feng Luzi and Ma Wanhai. When the Japanese army invaded, Colonel Ozaki led his troops to Fenglingdu. This man looked gentle and kind on the surface, but he implemented cruel policies as soon as he arrived, forced enslavement of education, and shot Mr. Zhou who was teaching. Black Grape went up the mountain to join Xiao Beifeng in order to avenge his country and his family. Xiao Beifeng's brothers were influenced by Black Grape's anti-Japanese war and pushed Black Grape against Japan.
