I got this from emrocks on the 22nd of last month about the holiday in China.
"Things start getting really crazy with China shipping from the holiday season up
through Chinese New Year, so there's about a 2 month period of time when everything gets congested there and things slow to a crawl getting out of customs. Everything in China shuts down on the 15th this year, as the Spring Festival begins the 15th and the new year is on the 23rd this year. The whole country shuts down starting 1 week before the new year, and resumes 1 week after."
Hope this helps some...I feel your pain
