Rain on Hengduan Mountain

In geography, high school students learned about the Hengduan Mountains, the Pacific Ocean, the Indian Ocean, the East Asian monsoon and the South Asian monsoon. What kind of romantic story will there be between them? Listen to me tell a story about water molecules. There is a small water droplet in each of the Pacific and Indian Oceans. They know each other and are eager to meet. Although there is only one millimeter between them, they cannot blend because of the different salt content of the two oceans. One day, a southwesterly wind blew over the Indian Ocean and a southeasterly wind blew over the Pacific Ocean. They were carried by the wind and thought they would never meet again, but later they fell to the ground as rain in the Hengduan Mountains, and finally they met again in the mountain stream. Isn't this time very romantic? Unfortunately, the probability is so small that it can be almost ignored. What's worse is that almost everyone's life has unfortunately become the thousands of small drops of regret instead of the only two small droplets that meet again in the end.
