Only at the entrance of Moldoga Forest Park did we know that because of the road construction inside the park, private cars were not allowed to enter, so we could only take sightseeing trains (100 tickets per person, no tickets). The train stops at five scenic spots: forest park, pine forest, garden forest sea, Linxi waterfront, forest pasture and so on. The soft mountains are reflected in the clear water, and the bright unknown flowers are accompanied by the tall pine forests. Only in this forest garden can we fully understand the beauty of the Great Hinggan Mountains. Regrettably, it was called back again and again by the eager train whistle, unable to slow down and enjoy the intoxication.
