The origins and stories of the four meritorious officials, what are their names and status? Thank you, God, please help me.

In ancient Chinese Feng Shui, there are many gods related to it, and the Four Values ​​of Gongcao is one of them. The four-value Gong Cao are the four little gods believed in Taoism who are responsible for the year, the month, the sun, and the time. Gongcao is originally the name of an official in the world. In the Han Dynasty, he was the assistant to the governor of Zhou County, and had titles such as meritorious officer and meritorious official. The main job is to inspect and record merits and manage the merit list. Later generations continued to use it and it was not abolished until the Ming Dynasty. When Taoist theorists weaved the world of gods and immortals, they also equipped high-level gods such as the Jade Emperor with this official position. In Journey to the West, Sun Wukong made a big fuss at the Peach Fair and betrayed the Heavenly Court. The Jade Emperor was furious and sent Li Tianwang to lead the four heavenly kings, Prince Nezha, Twenty-eight Sus, Nine-Yao Star Official, Twelve Yuanchen, Five Directions, Four Directions, etc. On the merits, 18 dragnets were laid out in the lower realm to capture the demon monkey. Unexpectedly, in this fierce battle, the fourth-level meritorious officer fell into disgrace. The heavenly soldiers and generals were defeated miserably by the Monkey King. How could there be any merit to be remembered? Later, Erlang Shen was invited to capture Monkey King. In addition to being a merit recorder, the fourth-level merit officer also serves as a guardian general. In Journey to the West, they, together with the guardians Jialan, Liuding Liujia, Wufang Jiedi, etc., secretly protected Tang Monk in accordance with the Bodhisattva's decree. In addition, they also acted as heralds. When Tang Monk and his disciples crossed Pingding Mountain, the meritorious officer on duty turned into a woodcutter and informed them of the news so that they could prepare in advance. Among the four merit officers, the one with monthly merit is the most tiring, because he is on duty every day, so he is called the merit officer on duty. In classical novels, when describing the practices of mages and Taoist priests, they often ask: "Where are the merits of being on duty?" You must be on call, you must not be lazy, how can you not be tired? Gong Cao is a scribe, so the Taoist priests will not let them idle. They claimed that all inscriptions that "reached heaven" in the human world were "presented" by the fourth-level meritorious officials after being burned. In Jin Ping Mei, it is written that the Taoist priests laid out many documents and talismans for the Ximen Qing Yuhuang Temple. One of them was to ask the meritorious envoy to "play the three-day gate to convey the customs". In Dream of Red Mansions, Qin Keqing held a grand funeral after his death, and the monks and Taoists also followed similar procedures when chanting sutras and performing rituals. The Plum in the Golden Vase and The Dream of Red Mansions are true portrayals of social life in the Ming and Qing dynasties. The belief in the four values ​​of merit by Taoism and Taoism can be seen here. Today, the school still retains the title of "duty students", but only borrows some functions of "duty meritorious students" and eliminates the feudal superstition.
