Please inform if the Chinese New Year Holiday starts January 5th.?? how long does it lasts?

Hello,

I leave in Shanghai and the CNY or the Spring Festival ( same thing) starts on the 10th of February this year for one week. We will be travelling to Beijing to visit the Forbidden city and the Gréât Wall , we expect to be shoulder rubbing everywhere. The Golden weeks are very busy and probably not the best time to visit these famous places . If you plan to visit China avoid these périods.
Best,
