It's about an incident that happened on the streets of Stockholm on 1650. 52-year-old Descartes met 18-year-old Swedish princess Christine. Descartes was down and out, and he was unwilling to beg for alms from others. Every day, he just studies math problems with a broken pen and paper. One day, Christine's carriage passed by the street and found Descartes studying mathematics. The princess got off the bus and asked, and finally Descartes found that the princess was very talented in mathematics. A few days after his farewell, Descartes was told that the king wanted him to be Princess Christina's math teacher. In the following years, Descartes and Christine fell in love, and the king found and killed Descartes. In Descartes' last love letter to Christine, the mathematical coordinate equation of r=a( 1-sinθ) appeared, and it was solved into a heart-shaped pattern, which is the famous "heart line". This love letter was finally collected in the Descartes Museum in Europe.
The advertisement of "Hundred Years Old Mountain" makes us feel beautiful, noble and happy. Of course, beauty and happiness are their favorite. Nobleness lies not only in the identity of Princess Christine, but also in her noble character and beautiful vision. Compared with the story behind Hundred Years Old Mountain, it is sad and regrettable. ......
I still can't forget Christine's gentle eyes when she looked at Descartes in the first advertisement of "A Hundred Years Old Mountain", which made Descartes feel pious, as if he had met the dawn of life. ......
In the third advertisement of "A Hundred Years Old Mountain", that lovely girl has the same dignity and vision as Christine, so she has the same "unforgettable" encounter as Christine. When she looked at the girl with gentle eyes, I felt that the advertising creativity of "Hundred Years Old Mountain" gave Christine a "happy ending"!
