Tour on time, long on actual trip, total tour time in chu chi 2 hours, pp trip 4 hours. The tour guide is very informative, the English language is quite understandable ... it is enough to improve the pronunciation so that later tourists can understand it better. The history of chu chi is very interesting and explained very well by the tour guide. Friendly tour guide. The tour provider may be able to provide anti-mosquito cream to repel mosquitoes because there are quite a lot of vicious mosquitoes in Chu Chi.
