Is here any service provided for luggage storage in Shenzhen Baoan Airport?

I am flying to Shenzhen arriving at 12.30pm and then to Xiamen at 10.00pm the same day. I intend to make a short visit to 'Spendid China' and 'Window of the World'. Please let me know is there any service provided for luggage storage in Shenzhen Baoan Airport,
