I stay at Starpark Hotel at zhongxin Road , shajing Bao'an district in Shenzhen, how I can get guangzhou airport

From where you are, you can take a taxi to Shajing Central Bus Station, where you can find frequent buses for Guangzhou Tianhe Bus Station. You need to get off the bus at Tianhe Bus Station, where you can find the Guangzhou airport shuttle bus line 8A1 and take it to the Guangzhou airport.
