Echoes Across Time and Space

In 1992, in Shanghai, China, Fang Yiming, a graduate student in the Department of Mathematics at Fudan University, and his father were sorting out his grandfather's belongings when they discovered the belongings of his great-grandfather Fang Renyu who died young. Among the relics, in addition to some manuscripts and unfinished graduation thesis left by my great-grandfather, there is also a Shoushan stone seal ring engraved with the word "Seeking Truth". Fang Yiming loved this ring very much, and after obtaining his father's consent, he put the signet ring on his hand. From then on, he established a strange connection across time and space with his great-grandfather. In another time and space, in 1912, at the University of Wisconsin Hospital in the United States, Fang Renyu, the first Geng Scholarship student studying in the United States, was unconscious on the hospital bed. As he lay dying, a red light seemed to flash from the seal ring on the ring finger of his left hand. Fang Renyu, who died young, miraculously had a fever, and his vital signs gradually stabilized. After waking up from a coma, Fang Renyu found that he had inexplicably a lot of knowledge in his mind that he had never learned and mastered before. He believed that this was a revelation, a gift from God to enable him to better complete his mission. A mysterious ring connects two parallel times and spaces. From 1912 to 1945, and from 1992 to 2025, two time tracks move forward in parallel. Using knowledge as a bridge and ideals as sails, they jointly wrote a legend that spans a century - This is a hymn dedicated to all those who explore the truth in loneliness and pass on fire in the darkness. The true inheritance has never been cut off by time and space; the deepest echo can penetrate all darkness.
