Prince William, Kate Middleton, Prince Harry and Meghan Markle need to do some preparations before starting their royal tours.

The Duke and Duchess of Sussex made their royal tour to South Africa last month. Meanwhile, the Duke and Duchess of Cambridge just culminated their trip to Pakistan on Friday.

According to Lauren Clark of The Sun, as the Queen’s official representatives, the fab four have to ensure that they give the best impression possible. Thus, they also prepare for their trips.

Among the things they do is to learn the local greetings as well as other vocabulary in the country’s native tongue. Learning these things is very helpful especially that they attend a string of engagements where they are required to interact with locals.

“The internal palace aids will always be on hand to prepare each royal before an important visit,” etiquette expert Myka Meier said.

“It is the correct protocol to practice the etiquette of the country or culture you are visiting, in order to show respect, so each royal knows how to make the best first impression.”

Earlier this week, Middleton impressed many when she spoke using Pakistan’s official language, Urdu. The duchess used it when she delivered a speech at the SOS Children’s Village, a charitable organization which provides a home for 150 orphaned young girls and boys.

Prince Harry and Markle were also expected to brush up their knowledge on the local dialect of South Africa ahead of their tour. However, since the country has 11 official languages with English being the fourth most common after Zulu, Xhosa and Afrikaans, they had to learn a broad sweep depending on the locations they visited.

Prince Harry and Markle’s South Africa tour was deemed successful even before it ended. Many were convinced that they had redeemed their reputation after enduring negative headlines all year long, but the couple lost their glory in days after starting a war against the press.

Meanwhile, Prince William and Middleton’s Pakistan tour was also praised. In fact, Katie Nicholl said that they might receive a congratulatory letter from Queen Elizabeth II.
