The title broadly mentions 'Shenzhen', but the rules strictly limit the measurement to the 'Shenzhen Bao'an International Airport Station (ZGSZ)' using Wunderground as the sole resolution source. It also specifies rounding to whole degrees Celsius. Traders relying on alternative weather apps (like Apple Weather or official CMA data) could easily misjudge due to microclimate variances between stations.
