The article is generally reliable and trustworthy, as it draws on official data from the Beijing Municipal Center for Disease Control and Prevention and interviews with experts such as Zhang Daitao. However, there are some potential biases that should be noted. For example, while the article does mention high-risk groups such as children under 5 years old, it does not provide any information about other vulnerable populations such as pregnant women or people with weakened immune systems who may also be at risk of infection. Additionally, while the article does provide advice on how to protect oneself from infection, it does not discuss any possible risks associated with taking preventive measures such as wearing masks or avoiding large gatherings. Furthermore, while the article mentions that crowd mobility has increased due to school reopening, it does not explore any counterarguments or consider any other factors that may have contributed to this increase in activity. In conclusion, while this article is generally reliable and trustworthy overall, there are some potential biases that should be noted when considering its content.
