In May 2008 12, a few days before the earthquake, I bought China Oil. I remember that the highest price that day was mine, 18.98 or 18.97 yuan, which can be found. Unexpectedly, about 2, 3 days or a week later, the 5. 12 earthquake suddenly struck, and I directly cut 47,000 yuan at the opening of 13 that day, and was out. Its issue price seems to be 16, 70 yuan. 18.98 and 16.70 are very close, so it must have fallen below the issue price in 2008.
