What does it mean to classify biosafety levels?The biosafety level was a classification standard determined according to the different degrees of biological harm. The significance of this was to distinguish the risk standards for scientific research in the laboratory. It could also be regarded as a standard for judging the degree of biological harm.
The biosafety levels range from BTL- 1 to BTL- 4, which are classified according to the potential harm of the organism to human health and the environment:
- BTL- 1 (Level I risk): Low individual risk, low group risk. The microorganisms involved (such as bacteria, fungi, viruses) and parasites (such as non-pathogenic biological factors) will not cause diseases to health workers or animals.
- BTL- 2 (Level II risk): Individual risk, group limited risk. These organisms can cause diseases in humans or animals, but under normal circumstances, they do not pose a serious danger to health workers, groups, livestock, or the environment. Laboratory exposure rarely causes serious diseases, and there are effective treatments and preventive measures. The risk of transmission is limited.
- BTL- 3 (Level III risk): Individual high risk, group low risk. A pathogen that can cause serious diseases in humans or animals or cause serious economic losses, but usually cannot be transmitted between individuals due to accidental contact, or can be treated with antibiotics and antiparasitic drugs.
- BTL- 4 (Level IV risk): Individual high risk, group high risk. It can cause very serious diseases in humans or animals. It is generally incurable. It is easy to directly or indirectly or accidentally contact the pathogen that spreads between humans, animals, and animals.
This division helped to prevent the spread of viruses and take corresponding prevention and control measures for different levels of biohazard. At the same time, different biosafety levels also corresponded to different laboratory safety level requirements. The purpose was to protect the safety of laboratory staff and the environment.

From the perspective of some viewers and reviews, it was not good. His Douban score was 6.6, down from 7.8 in the first season. There were problems with the plot, such as following the cliché of ancient puppet dramas, disrupting the story and character foundation of the first season, and creating a tragic love atmosphere that was considered to be a dog's tail. In terms of character creation, she felt like she had been reduced to a tool. The setting of abuse for the sake of abuse was full of loopholes. For example, some of Xiaoyao's plot directions seemed unreasonable, such as choosing to marry Redwater Prosperity in order to help her brother's career rise, and breaking off the marriage on the day of the wedding. The plot was also dragged out and filled with water, making people feel physically and mentally exhausted. It was also difficult for people to understand the scriptwriter's intentions. In terms of acting skills, there was a point of view that the female lead, Yang Zi, did not perform well in some emotional scenes.
However, there were also opinions that it was worth noting. It could be seen as a drama with the main female lead. Xiaoyao was the main storyline and witness of the plot development, taking responsibility for everyone's happiness. In the plot setting, there was an intersection between reality and fantasy. Clearwater Town symbolized fantasy, while walking out of Clearwater Town meant facing reality. The change of character and emotional pull made the plot even more exciting. In terms of character design, the female lead, Xiao Yao, went from escaping to taking responsibility. The character design gradually became more and more wonderful. This emotional pull also made more people willing to watch and increased the popularity of the drama.
