古力
Around 226, Sun Quan had a large vessel constructed in Wuchang and he named the ship "Chang'an" (長安). He sailed on it towards Diaotaiyi (釣臺沂) but encountered a storm along the way. Gu Li then ordered the crew to head towards Fankou (樊口; northwest of present-day Echeng District, Ezhou, Hubei). Sun Quan said, "We should go to Luozhou (羅州; present-day Huazhou, Guangdong)." However, Gu Li brandished his sword at the crew and threatened, "I'll execute any person who does not go to Fankou." Upon reaching the port at Fankou, the storm had not subsided yet so they remained there. Sun Quan then asked Gu Li, "Were you afraid of the river?" Gu Li knelt down and said, "Your Majesty is the master of thousands. You should not venture into treacherous waters and brave the storm. The ship may be large and steady, but if you encounter danger, what will happen to the state? That was why I strongly objected (to sailing towards Luozhou)." When Sun Quan heard that, he respected Gu Li even more and started calling Gu by his surname since then.
