Sample itinerary

Would this visa work under the following two scenarios:

1. Primary flight is Vancouver, Canada to Colombo, Sri Lanka, with a stopover in Hong Kong. During the stopover, we would fly to Shanghai (4 days), Seoul (5 days) and then back to Hong Kong.

2. Primary flight is from Vancouver, Canada to Colombo, Sri Lanka, with a stopover in Seoul. During the stopover in Seoul, we would take a side trip to Shanghai (4 days).

Thanks!
