On September 27-29, a group of us (Li Jun, Shizhen and Gan) paid anotrher visit to Ningbo Atmospheric Environment Observatory (NAEO) first setup by the group from 2008.  Chen Yingjun, from Shanghai, and Zhang Yanlin, form Nanjing, came to meet with us for a dinner together in Ningbo.  The NAEO was first setup by Zhang Yanlin, and then built by Liu Xiang and Li Jun. It has been taken care of by the ‘Shen brothers’ who have been very professional to keep the station running for 12 years! The facility needs another round of refurbishing.    Besides, we also visited the famous Tiyige (天一阁）in the city, which is an ancient library, amazing.
