The Koi constitution that surpassed her younger sister was a myth. It seemed that she was lucky enough to avoid all misfortune and setbacks and continuously obtain the protection of success and good luck. However, this kind of physique is not completely real. We can't be sure if she can really control her own fate. Although the Koi constitution could not be proven to exist, it could indeed bring hope and courage to people under certain circumstances. It reminds people to maintain a positive attitude even in the face of difficulties and challenges in life, believe in the existence of good luck and opportunities, and work hard for them. Although her koi constitution that surpassed her sister's did not represent all lucky things, her success and recognition through her own efforts and perseverance had also brought some enlightenment to people. For those who wish for good luck and success, the Koi constitution that surpasses their sister can serve as a good role model to encourage them to continue to strive, believe in their own abilities, and actively face the challenges in life.
