We ordered a one-way ticket. We had to enter the entrance from Pudong. The entrance is at Fenghe Road. In the past, people who took Metro Line 2 should take the overpass to Fenghe Road. The road sign is very eye-catching, near the Oriental Pearl. Tourist tunnels, bus rides, three minutes of the whole journey, like a light show, with explanation, the effect is OK, but the price is a bit high.
