Katê Festival

Cultural diversity is a vital aspect of any society, and festivals of ethnic groups play an essential role in preserving the cultural identity of a community. Embracing cultural values through festivals is an important way of staying connected with one community as well as its history and traditions, and a well-known Katê Festival of the Chăm people in Vietnam is an example to prove so.

The Katê Festival, also known as Mbăng Katê, is the biggest yearly festival for the Chăm people in Vietnam. It is a special time of year when they honour important figures in their history and the dead in their families. The Kate Festival takes place on the first day of the seventh month in the Chăm calendar, usually in September or October. It lasts for three days and takes place around three important ancient structures in Ninh Thuận Province: the Po Klaung Yăgrai Tower, the Po Romé Tower and the Po Inû Nagar Temple. All of these places are very important to Champa culture and history.

On the morning of the first day, Cham families take part in processions as they travel to the towers and temple, bringing gifts of fruit, meat and rice. In a special ceremony, the Cham people receive the costumes of the Goddess Po Nagar from the Raglai people, a cultural group with close connections to Champa culture. The Chăm carry the costumes to the temple to celebrate Po Nagar, then they open the gates. Inside the temple, they start bathing the statues of important figures and watching sacred dances. After those performances, people enjoy lively parties until the evening of the festival's second day.

On the last day, people make special offerings to their gods at community houses in their villages and pray for luck and good health for the coming year. Once this is over, there are traditional music performances, and then people do fun activities like playing football and participating in weaving competitions.

Read the passage carefully.

1. It is estimated that about 40 per cent of the world's population use social media, and many of these billions of social media users look up to influencers to help them decide what to buy and what trends to follow. An influencer is a person who can influence the decisions of his or her followers because of his or her knowledge or special knowledge in a particular area, e.g. fashion, travel, or technology. Influencers are now seen by many companies as a direct way to customers' hearts. Brands are now asking powerful influencers to market their products. With some influencers charging up to $25,000 for one social media post, it is no surprise that more and more people are keen to become influencers, too. If you are one of them, then here are five tips on how to do it.

2. Choose your niche: What is the area that you know most about? What do you feel most excited talking about? Find the specific area that you are most interested in and develop it.

3. Choose your medium and write an interesting bio: Most influencers these days are bloggers and micro-bloggers. Decide which medium – such as your own online blog, Instagram or Snapchat – is the best way to connect with your followers and chat about your niche area. When you have done that, write an attention-grabbing bio that describes you and your speciality area in an interesting and unique way. Make sure that people who read your bio will want to follow you.

4. Post regularly and consistently: Many influencers post daily on their social media accounts. The more you post, the more likely people will follow you. Also, make sure that your posts are consistent and possibly follow a theme.

5. Tell an interesting story: Whether it is a photo or a comment that you are posting, use it to tell a story that will catch the attention of your followers and help them connectwith you.

6. Make sure people can easily find your content: Publicize your posts on a variety of social media by hashtags and catchy titles to make sure that they can be easily found. There is no point writing the most exciting blogposts or posting the most attractive photographs if no one is going to see them.

7. Most importantly, if you want to become a social media influencer, you need to have patience. Keep posting and your following will gradually increase. Good luck!
