"Liaohua is a pioneer" comes from Shu, the Three Kingdoms, which means that people are frustrated and helpless when they arrive. In the middle and late period of the Three Kingdoms, with the continuous decline of the national strength of Shu, the number of outstanding generals in Shu was also decreasing. But Zhuge Liang's Northern Expedition continued, and Shu was so short of elite soldiers that Zhuge Liang could only send Liao Hua with low ability.

The whole sentence: "There is no general in Shu, and Liao Hua is the pioneer". During Jiang Wei's Northern Expedition, all the generals in Shu who were good at fighting had died, and no one was available. Liao Hua, who was nearly eighty years old, could only be a pioneer. The original intention is that Shu doesn't even have a young general, and a veteran like Liao Hua has to be a pioneer. Now it is often said that there are no outstanding newcomers in the team, and experienced old people are needed to shoulder the heavy responsibility.
