Table schema:
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?
SQL: SELECT MIN(nanquan) FROM table_name_40 WHERE rank > 2 AND total < 18.36 AND nangun < 8.85
