you can just stay in the city and find a quiet pagoda in D.5 for reading, too. I like reading in the pagoda because of the peace there. Have a nice time
Yeah the park in D7 is very nice and quite. It is safe since this area has securities 24/7 but that's why I'm not sure if they allow you to sleep there.
Pagoda means strange Chinese tower. Wait, I thought Vietnamese people hate the Chinese? If that is the case, why do they have China Town and Chinese Pagoda buildings in Vietnam? I do like the Chinese and I love Jackie Chan.
