I am a Singapore citizen. I will be going to Shenzhen and then to Shantou and acouple of other places and then back to Singapore via Shenzhen totalling about 17/18 days. While in Shenzhen,I need to go for short day trips to Hong Kong on two different dates. My questions are : 1. If I leave and return to Shenzen again within the same day,do I need to comply with any requirements.
2.Will the return from Hong Kong back to Shenzhen be recognised as a new visit and thus be allowed a 15 days visa free visit.
