That poem about guessing age, a week or half a century; The ancient and rare celebration is still 30 years old.

A week is 60 years, and the remaining half hundred is 50 years, 1 10 years old. Ancient rarity 70, two ancient rarities in Shuangqing, 140. It's a bit ambiguous if you still owe it. If you owe 30 to 140, it is 1 10. If 140 still owes 30, it is 170. I think it should be the former. Like the first part, 1 10 is years old, which is the most reasonable.
