The river froze in' 79, and swallows flew in' 89.

99 plus 19, plowing cattle everywhere. "

Hit six or nine heads in spring, take off your coat and change to a cow;

In 7963, pedestrians relaxed their clothes;

Nine times out of ten, don't plow, just stay for three or five days;

Yang Hua blooms in September and doesn't come in September. "
