Seek the best route from Shenzhen to Mohe in Harbin, Changbai Mountain in rime island and back to Changsha? thank you

1. The first morning, I flew from Shenzhen to Harbin. The train (K704 1 Harbin Station 18:22) arrived at Mohe that night and arrived at Mohe the next morning. You can join the Mohe three-day tour group.

2. Take the train on the evening of the fourth day (K7042 Mohe Railway Station leaves at 20:05) and arrive in Harbin at noon on the fifth day. You can take a self-help tour in Harbin city for half a day (if half a day is not enough, you can add one day by yourself).

3. On the sixth day, a seven-day tour of the Northeast Ring Road, including Xiang Xue, Xuegu, Changbai Mountain and rime island. You can play with snow, ski and soak in hot springs. On the last day, the general arrangement is to visit rime island in the morning and then send it to Changchun Longjia Airport. /kloc-You can fly back to Changsha after 0/4: 00.
