The origin of the allusion about the number one scholar and his younger brother Porridge:

According to folklore, Lun Wenxu's family was poor when he was young and he had to grow and sell vegetables to make a living. The owner of a porridge shop felt pity for his youth and talent, so he bought a load of vegetables from Lun Wenxu every day and asked him to deliver it to the porridge shop. When Lun Wenxu delivers food to the porridge shop, the boss will boil the leftover ingredients into raw porridge, add some ginger, green onion, etc. and treat him to it for free. For several years, Lun Wenxu ate porridge at the porridge shop every day and was very grateful to the boss. Later, Lun Wenxu won the first prize and went to thank his boss when he returned home. Since the porridge had no name, the boss asked Lun Wenxu to name it. Lun named the porridge "Zhuangyuan Jidi Porridge" and wrote a plaque for the porridge shop in his own hand.
