I think the "six qi" you asked is the same as the "six qi" in the "five movements and six qi". Luck theory is to study the ancient climate change in China and its relationship with human health and diseases. In Qu Yuan's The Journey to the West, "drinking cold water to eat six qi, eating light summer to wash zhengyang" is an early record of China people's ancient health-keeping method of "being convinced over the valley". "Being convinced and avoiding the valley" is supplemented by guided breathing without eating, so as to increase the curative effect and improve the level. Ci Hai said: "Bigu" is also called "Broken Valley" and "Juegu", which means not to eat whole grains. "Eating gas" is also called "inhaling gas" and "swallowing gas".

Therefore, I think the ancestor Qu Yuan may envy the immortal's state of living only by the essence of heaven and earth without eating or drinking. .
