Why is Chinese characters encoded in json stored in the Mysql database garbled?

Why is garbled Chinese characters that store json codes to Mysql databases? The json code is as follows: "\ u6768 \ u6865 \ u6e56 \ u5927 \ u9053 \ u7a0b \ u6768 \ u6e7e", but after Mysql is stored, it becomes "success ", "\" does not store json-encoded Chinese characters in the Mysql database. why?
The json code is as follows: "\ u6768 \ u6865 \ u6e56 \ u5927 \ u9053 \ u7a0b \ u6768 \ u6e7e ",
However, the Mysql storage becomes: "u6768u6865u6e56u5927u9053u7a0bu6768u6e7e ",
The "\" is missing. what is the cause of this situation? how can this problem be solved ......
Mysql json shared:
------ Solution --------------------
\ Value escape character, so it must be escaped during warehouse receiving
Addslashes ("\ u6768 \ u6865 \ u6e56 \ u5927 \ u9053 \ u7a0b \ u6768 \ u6e7e ")
------ Solution --------------------
We recommend that you use serialize () to serialize and store it again. of course, you can also store json strings.
