Zhang's conjecture 1: What is the orb? It is an extraterrestrial object, which has been falsified; dragon-veined dragon beads are doubtful; and it is a wonder of heaven and earth, yet to be proven. Zhang's conjecture 2: The expansion started from the appearance of the first ray of sunlight, which has been confirmed. Zhang's conjecture 3 , there is no pulling force within the expansion range. This was also verified when Zhang Mo entered the expansion range. Zhang's conjecture four, the hairspring was produced... Zhang's conjecture five...
