In the Romance of the Three Kingdoms, the weapon used by Guan Yu, the Green Dragon Crescent Blade, was reputed to be world-famous. Its weight reached about 28 kilograms. However, there were other characters in the novel whose weapons were heavier than Guan Yu's Green Dragon Crescent Blade. For example, during the Battle of Changban Slope, Zhang Fei, the general of Shu Han during the Three Kingdoms period, used a weapon called the Giant Snake Spear, which weighed about 25 kilograms. In addition, Lu Bu, the general of Dongwu, had also used a weapon called the Heavenly Halberd, which weighed about 30 kilograms. Although these weapons were heavier than Guan Yu's Green Dragon Crescent Blade, they were also one of the famous weapons at that time, with considerable power and collection value.
