15 days visa free for cruise group starting from Beijing and leaving from Shanghai

As a Malaysian citizen who resides in London, would like to take a packaged cruise holiday. Its journey starts by air from London to Beijing for 3 days, then by air to Sian for 2 days and then by air to Shanghai for a cruise ship leaving from Shanghai and all the way to Singapore. Any possibility of getting 15 days visa exemption? Thank you.
