What spirit does eating steamed bread and pickles embody?

Diligence. The main significance of eating "pickles steamed bread" collectively is to improve everyone's fighting spirit, feel the hard-won life, sum up the past and look forward to the future. More than a decade ago, the so-called suffering mostly referred to physical suffering, but now it has too many dimensions. Only by learning to suffer from loneliness, thinking deeply about the suffering of the spirit, and self-discipline to eat the suffering of the spirit can we widen the gap with others.
