B
Once in Hebei, two different families each adopted(领养) a twin girl when the girls were just ten days old. The girls grew up in the same city. However, for seventeen years, they didn't know each other.
Then, one day, one of them heard from a classmate that a girl working at a clothing store looked exactly like her. She decided to go to have a look. The first time she saw the girl's face, she felt close to her.
After talking, the girls discovered that they shared the same birthday and had the same taste in food. They even had the same voice. Soon, they became best friends and talked about everything. However, their adoptive（收养的）families both kept the truth secret（秘密的）from them.
After being best friends for 14 months, the girls finally learned the truth from their families: they were twin sisters! To decide who should be the elder sister, they played a game of rock-paper-scissors. Later, they learned that the game's result was exactly the same as their actual birth order.
▲ The sisters each bought an apartment in the same neighbourhood without planning it. And their 13-year-old children even ended up in the same class! Now, the sisters sometimes attend school meetings, and their children's teacher finds it hard to tell one from the other.
Twenty years after their reunion（团聚）, the sisters still feel thankful for finding each other. In 2025, they shared a message online, “Let's look forward to the next twenty years together.”
