This is the way I took by bus everyday to go to school near Dongsi. Choosing between a public bus (less crowded but no way to sit because many old people were taking it) or private bus, very crowded, but with good chances to find a seat. It took an hour everyday, for some 7 km?!

这是我2005年去上课的路线。从甘家口到历史胡同，坐一个小时的公共车。坐103路，没有很多人但是老人多所以没有坐位。坐846路也可以，但是人特别多。那个车快，坐位多。
