The strange spring on Yilu Mountain is two naturally connected waist-deep pools. Although they look like two pools, they are actually in one spring. All year round, regardless of drought or flood, its spring water is as quiet as a virgin, never rising or drying up.

For many years, Yilu people and even Haizhou people have walked hundreds of miles to get holy water from strange springs because of its miraculous effects. Up and down the mountain, there are villagers whose ancestors drank the spring water. The old ones have sharp ears and eyes, the middle-aged people are strong, and the young people have extraordinary intelligence.

Scientific tests have shown that Qiquan water not only strengthens the heart and spleen, prevents and cures diseases, lowers blood pressure and lipids, balances qi and blood, but also develops intelligence, enhances memory, and inspires thinking.

After a period of deliberation, Yilu people inherited their traditional advantages, used traditional craftsmanship, and built a new soy sauce factory based on the daily rise of Qiquan water. This is the "Qiquan" brand that is now famous inside and outside the province. Soy sauce production plant. The State Trademark Office directly approved the inclusion of "Qiquan" brand soy sauce as a national food registered trademark.
