Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_40 (nanquan INTEGER, nangun VARCHAR, rank VARCHAR, total VARCHAR)

### Question ###
WHAT IS THE LOWEST NANQUAN WITH A RANK BIGGER THAN 2, TOTAL LESS THAN 18.36 AND SMALLER THAN 8.85?

### Accurate SQL ###

SELECT MIN(nanquan) FROM table_name_40 WHERE rank > 2 AND total < 18.36 AND nangun < 8.85
