What is the source of the "second goal"?

The Second Plum Blossom is from the traditional Chinese opera The Second Plum Blossom!

The weather was bad that day, and dark clouds covered the sun, which made Mei Liangyu feel particularly bad. The imperial examination tour will start tomorrow. It is the only way to avenge the imperial examination. Looking back on that year, the weather was overcast. Treacherous court official framed his father and was saved by luck, so he came to Chen Risheng's house. This is the season when plum blossoms are in full bloom. Miss Chen came to hold my hand. "Do you want my brother to play with me in the future?"

From then on, Mei Liangyu began to study hard, and if she wanted revenge, she had to get ahead in the imperial examination. Just then, the blooming plum blossoms were scattered by the sudden storm. Mei Liangyu suddenly lost confidence. At this time, Chen Risheng and Chen Xiaomei came to Chen Liangyu and said, "Come on, let's go to the backyard and worship Brother Mei." Chen Xiaomei walked up to Chen Liangyu, took his hand and said, "Brother, let's go." Mei Liangyu, Chen Risheng and Chen Xiaomei came to Meiyuan in the backyard and began to worship, when the wind and rain suddenly stopped!

The next morning, Mei Liangyu got up and suddenly found out! The plum blossoms in the yard are competing to open, and they have opened twice! Thinking this is a good sign, Mei Liangyu regained her confidence and studied hard, even harder than before.

Time flies, several years have passed, and Mei Liangyu has become brilliant. I rushed to Beijing with a lot of knowledge to take the imperial examination. On the day the list was published, Mei Liangyu's name finally topped the list.

This legend evolved into the later drama "Ermei", and Ermei is also widely known! It represents the reappearance of beautiful things and also warns people that life needs hard work.
