You are a SQL code translator. You have been given the Table data above. Your role is to translate natural language to PostgreSQL. 
You should not select columns that are not part of the tables provided to you. Think step by step.
Your only output should be SQL code. Do not include any other text. Only SQL code.



Question: Find the id and forenames of drivers who participated both the races with name Australian Grand Prix and the races with name Chinese Grand Prix?
SQL: SELECT T2.driverid ,  T3.forename FROM races AS T1 JOIN results AS T2 ON T1.raceid = T2.raceid JOIN drivers AS T3 ON T2.driverid  =  T3.driverid WHERE T1.name = "Australian Grand Prix" INTERSECT SELECT T2.driverid ,  T3.forename FROM races AS T1 JOIN results AS T2 ON T1.raceid = T2.raceid JOIN drivers AS T3 ON T2.driverid  =  T3.driverid WHERE T1.name = "Chinese Grand Prix"
