What is the shortest and most convenient way to drive from Dalian to linkou county, Mudanjiang City? Ask good people for help.

The road surface in Jilin section is very good, which was repaired six years ago, and in Heilongjiang section it was repaired three years ago and last year. It turned out that the Heilongjiang section was a mountain road, and now it is a two-way expressway, no problem! From Changchun to Dunhua to Mudanjiang and then to Linkou. Just pay attention to the weather, it often snows, and you are afraid of road closures. If it doesn't snow heavily, don't worry about it! Save 100 kilometers! Note that I said the situation six months ago. Some people say that the Jilin section has been expanded. I wonder if there is any expansion.
