Introduction
Under normal circumstances, a "huo zhu zi" (活珠子) is a product of an egg that is about to hatch into a living creature but has not fully developed, and it is generally edible. When consuming huo zhu zi, attention should be paid to selecting products that are from reliable sources, fresh, and hygienic. Avoid purchasing huo zhu zi with unknown origins or that have spoiled, to prevent gastrointestinal discomfort. Additionally, ensure the huo zhu zi is thoroughly cooked before consumption to avoid potential hygiene risks caused by insufficient heating.

Generally speaking, a "huozhuzi" (live embryo egg) is a product of an egg that is about to hatch into life but has not fully developed, and it is usually edible. A detailed explanation is as follows:

As a unique product of the egg hatching process, huozhuzi contains an embryo that has not fully developed, typically between 10 to 14 days of incubation. At this stage, the egg retains its basic nutritional components and also develops tender embryonic tissues during development. When thoroughly boiled or braised, huozhuzi not only retains the freshness and aroma of the egg itself but also offers a unique delicate and smooth texture from the embryo. Its flavor is distinctive and contains no significant harmful substances. It has long been consumed as an edible food item in various regions, and thus is generally safe to eat.

When consuming huozhuzi, attention should be paid to the following: choose products from reliable and fresh sources, and avoid purchasing huozhuzi of unknown origin or that has spoiled, to prevent gastrointestinal discomfort. It must be thoroughly cooked before consumption to avoid potential hygiene risks caused by insufficient heating. Overconsumption should be avoided, as it may increase digestive burden. Children, elderly individuals, and those with weaker digestive systems should consume it cautiously, selecting appropriate amounts according to their own digestive capacity to ensure food safety.
