It means the same as "xuè": a little blood has been shed. I vomited blood twice.

In ancient times, extended data were read into sounds, but now there are two pronunciations: xuè and xiě, and xuè is mostly used in written language. Xic is mostly used in spoken language and often used alone.

In ancient Chinese characters in China, blood is like the blood of livestock in sacrificial vessels. At first, it refers to the blood of livestock sacrificed to gods, and later refers to the blood of people and animals. Kinship extends from consanguinity to consanguinity, which is also a metaphor for strength and warmth.

All idioms that use "blood" as a morpheme to form disyllabic words or polysyllabic words are pronounced as xuè. The former is like blood, blood color, bloodshot, and blood veins, while the latter is like flesh and blood, big mouth, blood stasis and rivers of blood (note: the idiom "hit the nail on the head" may come from common spoken language).

Anyone who uses "blood" alone will read xiě, such as "blood all over the floor" and "blood face". In other words, read xuè in written language and xiě in spoken language. There is a typical example: "blood debt should be paid with blood." According to the above pronunciation method, the former "blood" is a morpheme, pronounced as xuè, and the latter "blood" is a separate word, pronounced as xiě.
