I have another bumper harvest today:

2-day entertainment: 7.01 buying seems to be a -7% plunge and decisive buying. At present, the floating profit is 9.9%. It depends on the situation tomorrow. It is a pity if the closing of the board at the end of the World War really becomes famous and eats meat with peace of mind;4 Zhongxin Fluorocarbon: 7.6% plunged into a high probability that it should be eating meat tomorrow. Congratulations to the fans who got on the bus;Personal views are for reference only! The stock market is risky, so be careful when entering the market! Buy and sell independently and be responsible for your own profits and losses! I wish you all make a fortune, praise, pay attention and share a wave of support, and don't lose money or get lost!

At present, it has a floating profit of 1.3%, and it seems that the situation will be lost tomorrow;1 Shanzi Hi-Tech: I reminded fans to throw high and suck low in the morning. I also bought 1% high at the limit price. Although I didn't throw the highest point, I still have a little courage. At present, I am floating 43%, and I will vomit some tomorrow.
