She then pulled out a calculator and tried to figure out how many hours I was in China for. I'll be in China for 4 days so I didn't understand the need to calculate it. Anyway the sheet was in Japanese but clearly showed hgh and pvg as 144 hours but i didn't see if it mentioned that it is 144 hours starting at 0:01 the following day. So while you may be compliant you might need time to make sure the agents understand when the 144 hour clock starts.
