Because the code of the Shanghai Composite Index in the early days was in the format of 1A0001，At present, there are still a very small number of users who use Feihu and are still accustomed to using the Shanghai Composite Index in the 1A0001 format.，However, the standard code of the Shanghai Composite Index in the data transmitted by the Tornado Market Interface is 000001，In this way, users will not be able to see the Shanghai Composite Index in Feihu stock software.。
