I'm Just a Little Bird

The difficult survival of a single mother is due to the evil consequences of love in the free era; the daughter-in-law lives in an unfree era, but there is no lack of vague yearning or expectation; restraint and laissez-faire are due to differences in consciousness, but resistance and protection are not limited to the changes of the times. People from two eras meet and sing the same song, but it has different meanings.
