There are generally three lines from Laizhou to Yantai: the northern line 206 Matang turns to Zhaoyuan Qixia. Xujiadian, the snake nest berth of the middle route post road, was merged into 204. South Line 307 Guojiadian Laiyang merged into 204. After the northern line leaves the Laizhou boundary, it is a ramp to Qixia, which is slightly more difficult. After Qixia city, the slope is gentle, there are several slopes near Fushan boundary, and then go to Yantai. There are several slopes in the middle line from Guo to Daotou, and then it is relatively gentle. Shewobo to Xujiadian is a small slope, and it is a gentle slope after entering 204. The slope of the southern line is not big. Laixi Boundary River has several slopes from Wu Jia to Nanshu, then to Laiyangping Road, and then into 204 to Yantai Great Gentle Slope. Road bikes are difficult to climb (compared with mountain bikes). It is challenging to take the south-central line and the mountain bike to take the north line. That's all I know. I wonder if it will help you.
