Touching modern filial piety story

1, there is a kind of fish called snakehead. When the old snakehead is temporarily blind after giving birth, the little black fish will wait around the old snakehead after birth, scrambling to drill into the mouth of the old snakehead one by one, sacrificing himself to hold his mother's stomach and express his filial piety. When the old snakehead's eyes can see again and catch food, the rest of the little black fish will leave.

2. In the dust, two elephants, one big and one small, run like hell. When the hunter's gun rang, the elephant fell and tilted like a landslide. The elephant, who could have run for his life, turned to his mother in the flying dust. The mother elephant finally fell down, and her huge body was just on top of the elephant.
