There is Longhe Square nearby, where there are buses to Huaguo Mountain (ticket 100 or so, I think) and Fishing Bay (ticket 40 or so), I'm not sure (I personally prefer Fishing Bay, I think it's a bit more fun than Huaguo Mountain)

To go to the market gully in the evening, Fishing Bay take 111 to the market gully, Huaguo Mountain take 12 to the bus on the Shenghu Road, and then take 103 to the market gully. The marketplace can be. Arrived to find a place to stay, later you can go to the sea side around (no tickets), look at the night view of the seaside

The next day to go to Liandao's Dashawan Baths (tickets 50), 33 bus terminal (is unmanned ticket buses, the ticket price of 2 yuan, be ready to change), Dashawan Baths and Suma Bay is connected to the baths can be done to play in the baths in the sightseeing bus to the Suma Bay (sightseeing buses 3-5 yuan, not sure of the price)

If you go back to Huaian at night, you'd better come back from Liandao early in the afternoon, take 33 road from Liandao and get off at Bayi Market, transfer 106 to Su Xin Express, the road takes more than two hours

Wish you have a nice trip!
