The literal translation of the title of this movie is: Deep emotions at a Little Island.
The classification of family of this movie appeared to be inaccurate, because the movie appears to be a love story, so it should be classified into the romance category. Certainly, romantic tales are not suitable for kids, at least kids of young age and this is why the family classification appeared misleading.
This movie does not have much social criticism in it but just a realistic reflection of the ordinary problem: in the era of reform, soldiers are losing favors to girls because military service cannot accumulate wealth like those private business owners.
