2nd Mar : First full moon after the Spring Festival. Yup! Today is 元宵节
Always loved to look at the navel of moon. Don't you think it resembles an orange's navel? Anyway, the proper name for this is Tycho - a crater
taken from wikipedia
is a prominent lunar impact crater located in the southern lunar highlands, named after the Danish astronomer Tycho Brahe (1546–1601).

Tycho stands out because it's still fresh with an estimated age of 108 million years, far younger than the 3.9 billion years for many large lunar craters. We know its date of birth because the Apollo 17 astronauts bagged a sample from one of the rays and returned it to Earth for study in 1972.
