In my case, immediately and for a short time after my release I was followed very closely and my movements were monitored very closely. But after that, the monitoring and the following me around has relaxed, but I am still subjected to harassment, and my family is also in the same situation.
On the other hand, I had a lot of difficulty trying to leave Vietnam. When I tried to leave Vietnam, I was detained for 13 hours without any food or drink. At the same time, whenever I moved about, I would notice that somebody was watching me.
