Sun Ru
In 885, Qin sent his general Sun Ru to attack Luoyang. Li battled Sun for several months, but eventually ran out of food supplies, so he abandoned Luoyang and set up his headquarters at Mianchi (澠池, in modern Sanmenxia, Henan), allowing Sun to seize Luoyang. However, Sun abandoned Luoyang after a month (after burning the palaces at Luoyang), and Li was able to take his army and return to Luoyang.
