1, riddle: white and round, like a table tennis ball, cooked in a pot, the whole family eats more than fifteen. (Answer: Tangyuan)

2. Mystery: As soon as Lao Zhao left, he changed completely. (Answer: Lantern Festival)

Analysis: "Lao Zhao" does not refer to Zhao's traditional character, that is, "Zhao"; After the word "Zhao" has gone, "Xiao" is still there. The combination of "filial piety" and "ten thousand" that has completely changed can become "Yuanxiao".

Second, the sentence about the Lantern Festival is:

1, eat glutinous rice balls on the fifteenth day of the first month: you are round, I am round, and everyone becomes attached! Japanese yen, full moon, everything is round! Human origin, happiness, and ubiquitous source! Official sources and financial resources are constantly flowing! Wish, wish, wish to be satisfied!

2. On the fifteenth day of the first month, there are many celebrations, many family members are reunited and happy, many happy friends, many healthy and happy bodies, many financial resources and a lot of good luck every year. How nice!

I wish you a happy life like dumplings, sweet love like stuffing, and smooth career like dumplings. In short, all loves, a happy life and a happy Lantern Festival!
