On May 5, the last day of the holiday, the researcher used the break time to remind people to be careful of the decline of No. 678, and emphasized the 100% decline. The fluctuations in the middle cannot be judged, and the direction is downward. On May 7, the market was updated, and the short position continued to be held, with the target of breaking 62000 and looking at 61x00. The lowest point this morning reached 62055. Congratulations to the friends who got on the train and made money.
