You mean Dr. Zhang Li. I am at 8-9 o'clock every night. If the deadline does not wait, rest on Friday and Saturday. You can also hang tags on the same day. As for how to get there, go north along the road from Dawangdian to Busan, meet the road near Xiaoheishan, go east into Qushui Village, go east along the road, go north at the end, and then go east and north for a while. His home faces east. Just go into the village and ask. Telephone 03 12-8967598. The appointment time may also be 7-8. I forgot. You can try, but it may not work at other times. You try. You need to call early, or you will miss it.
