An incredible Beijing

Having been in Beijing for more than 8 years as a Northeastern born Chinese ,"studying in the capital of my country " has also been a reality since I went into my college life in 2003 in Minzu University of China.
As the most diversified university in China ,I met different people here from Tibet ,Uyghur area ,Inner Mongolia as well as Chinese-Koreans,therefore, delicious foods also flew in my month and life.
During my stay in Beijing ,mother kept visiting me on a year-basis regulation ,and our stomachs enjoyed a lot of local and nationwide snacks,absolutely none of them could let my mom --a woman who was in her fifties' , to link food with the own experience ,until we stepped into that restaurant ,my mother opened the gate of her deep-inward.
"Red Classics" (Hongse Jingdian) ,if you were born in USSR, Eastern Europe or China ,you might be familiar with the exact mean of "Red" , this "culture-revolutionary" -featured restaurant appeals guests from all over the world .Just here, some images I often heard from my mom since my childhood came into alive on the stage.While eating "bitter-nostalgia" rice ,my mom became a talkative "red girl" , she told me how much credit they would earn on the soil field for the next month poor salary .The waiters and waitresses wore like they jumped from history.
Food and clothes are far to enough! With the emotional music and band ,the waiters and waitresses became the dancers of "Royal to Chairman Mao" ,the most famous piece during that "ten years" unforgettable period ,mom stopped moving her chopsticks and stood up slowly ,emotionally ,I also saw some other ladies in the similar age of my mom's .
They began to dance!
That was my first time to see my mother dancing on my own eyes! These ladies ,I was sure they were talking to themselves when dancing ,more specifically ,they were talking to "then" themselves.Every move,every bending,every eye-focus,they made perfect. Ten minutes ,dance over ,mother became herself again like the power inside has gone .“Wow, I never thought there was a restaurant in Beijing can put all these royal dances on the stage ".she said to me with an understandable calm down.
I was proud of myself that I led my mother here.She did not purely have a meal ,which means some dishes and service ,more importantly ,I gave her a chance to call back to a historical moment -which exclusive to her ,even though it was only ten minutes.
