At the construction site entrance, Zhao Mingyuan's ten-yuan box lunch had just opened when it ran into Lao Chen's twenty-yuan-a-portion "safe on the stomach." Zhao Mingyuan sold cheaply and served food fast, getting more and more orders; on Lao Chen's side, it was always those same few phrases. "The rules cannot be broken." "What to do with the leftovers? Throw them away." "Buy more meat tomorrow? No need, take it slow." "Finally getting better, hmm, must stay steady." Seeing the ten-yuan box lunch selling more and more hotly, "safe on the stomach" was also becoming increasingly burning on the mind. Customers became fewer and fewer, leftover food became more and more, and Lao Chen still guarded his own set of rules. Until his business concept did not match the market, thoroughly going bankrupt.
