Hi Mr Johnnash, thanks for your reply.
I just called Nanjing PSB office 84420005 and was told that the calculation of days is based on : starting from the following day of arrival. Appreciate your advice if my trip exceeds the 15 days maximum requirement. I took the 0115 24 July flight arrival Beijing 24 July 2010 0635hrs. I intend to leave on 9 August 0010 flight for singapore. Should be checking in on 8 August at about 2300hours. Pls advice. I was informed that this does not exceed 15 days. Appreciate your advice. Thanks.
