A polite way to show that you are ill.

The elegant expression of this situation can be "poor health" or "minor illness".

"Poor health" is a Chinese word, which means that people are unwell. It is usually used to show people's physical condition and show concern and respect for others.

"Minor illness" refers to minor illness or discomfort, and is usually used to describe minor physical discomfort. This word expresses the meaning that the illness is mild and not serious, and also implies that the patient needs proper rest and conditioning, and does not need to be too nervous and worried.
