There are five unique plaques hanging directly above the hall of Wan Kang Manor, which are not only the family instruction of Konka, but also the symbol of Konka Manor culture and the treasure of the town hall. "If you enter Kangwan, look at the plaque first". The beginning begins with "Liu Siming", a Taoist priest who stayed in France to farm: "More than enough, but less than enough, thinking skillfully and returning to the original; Leave more than enough to repay the court; Leave more than enough and inexhaustible wealth to repay the people; Wang Boda, a Taoist priest in the Southern Song Dynasty, has four mottos, warning future generations to leave room for everything. In this world, don't enjoy all the blessings, blessings and longevity, but leave them to those in need. Then, I quoted two words from Gao Jingyi, a scholar in the Ming Dynasty: "There is room for the first step; When the money is relaxed, there will be a aftertaste. "It can be said that the residual thoughts have been brought to the extreme. Finally, he concluded: "What if that generation knew how to run a family? Leave the rest to avoid. "The way to make a prosperous family is to' stay surplus and avoid it'. This sentence tells the secret of the prosperity of the Kang family for 400 years, that is, leave room for everything, avoid surplus and avoid fullness, and go too far. This thought is China's thought that "the sun will rise and the full moon will set" since ancient times, and it is also the concentrated expression of Confucian "golden mean" thought.
