Does anyone know how to get to Vladivostok from Shenyang?

Or know of a place that has better connections than SY? I will be coming from Hangzhou, and was planning to spend a day or two in SY and to proceed to Vladivostok afterwards. If you maybe know of a city from where it might be quicker, cheaper or in any way easier to reach Vladivostok please share. Thanks in advance.
