Table schema:
CREATE TABLE table_name_71 (hanzi VARCHAR, name VARCHAR, launch VARCHAR, language VARCHAR)

Question: Which hanzi's launch is before 2009, when the language was tibetan, and the name was qinghai tibetian general channel?
SQL: SELECT hanzi FROM table_name_71 WHERE launch < 2009 AND language = "tibetan" AND name = "qinghai tibetian general channel"
