My husband and I (seniors who love to travel) will be traveling to China in April. We will be visiting Beijing, Xian and Shanghai. I have been watching and reading this forum for what seems like months. I have read all of the travel guides available from our local library and have purchased the DK Eyewitness Guide. Our plan is navigate around to the various sights using the subway system and walking. I understand that cabs are inexpensive but would rather just avoid them if possible.
When we arrive in Beijing we plan to take the Airport Express to the Dongzhimen station and then take line 2 which has a stop near our hotel. We have a similiar plan for Shanghai and will use a shuttle bus in Xian. I recently read that Beijing and Shanghai have installed in the subways security system very much like those used at airports. These subway security systems are the reason for my question. We will each have a smal roller type suitcase that were checked for the overseas flight. Our luggage will contain things like curling iron (metal), mouthwash (liquid), etc. Will this present a problem with the subway security???
