Do I have to pay a deposit of 50,000 yuan to travel with a group to Taiwan Province Province?

Not necessarily! This deposit depends on the situation: generally, people who travel together do not need to pay a deposit: elderly people who travel alone plan to stay, and those who have relatives and friends in the local area must pay a deposit, for fear that they will stay in Taiwan Province Province without a ticket, so the Tourism Bureau will fine the travel agency, so the travel agency will collect this deposit.
