Thread Content

The event has ended. Thank you all for participating in this New Year’s celebration. I really wanted to give everyone something, but due to extremely low budget constraints, it was not possible to do so. So today I’ve prepared some safety questions for everyone. After you answer them, I will convert the quality of your answers into a certain amount of wealth to give to you. That’s all; I just hope that everyone in the chemical industry always keeps safety in mind. Note: 1. Due to my limited rating capabilities, there are few questions and the scores are not high; I hope everyone can understand ； 2. The total score after answering the questions is rounded off; for example, 10.5 units of wealth are counted as 11 units ； 3. Since I can rate only 10 assets per rating, for any number of assets exceeding 10, it will be calculated as: 1 charm = 9 assets ； 4. Answers should be provided in the form of replies to the post, including only the question number and the answer; otherwise, they will not be processed. I hope everyone will cooperate ； 5.
