MY TRACKENG STOPED WHEN IT ARIVED TO THE US UU544662355CN PLEASE HELP

My tracking LV358428025CN is stoped in ‘handed over the carrier’ since 3rd of December, more than two weeks. I don’t have news about it, where is it? Is this long period normal? How can I get information about it? When will be arrived to my country? I think it is too much days. Please contact me back. Thank you

I sent three boxes from Japan to Huizhou, Guangdong Province last month, but their shipping process has been stoped at Chinese Customs since June 4. The tracking number of my parcels are CN 104 990 714 JP, CN 104 876 507 JP, and CN 104 922 864 JP. They are the goods necessary for my life in China because I am now working in China for three years. Please examine the reason of this stop and tell me what I should do. Thank you.
