YouTubers Lee John Barrett and Oliver Joshua Barrett made their first visit to Chongqing on Friday, and plan to release a series of vlogs based on their 10-day travel through the municipality.

The British father and son duo runs the 'Barrett' YouTube channel, which has 117,000 followers and a total view count of over 9 million. They have been living in Shenzhen for years, with most videos depicting their everyday life in China.
