Table schema:
CREATE TABLE table_name_35 (number_of_clubs INTEGER, winners VARCHAR, fourth_placed VARCHAR)

Question: What is the number of clubs when Dalian Shide won and Sichuan Quanxing won 4th?
SQL: SELECT AVG(number_of_clubs) FROM table_name_35 WHERE winners = "dalian shide" AND fourth_placed = "sichuan quanxing"
