First, congratulations. Studying abroad is a craze in recent years, but not everyone has the opportunity. I hope he will cherish this opportunity to study abroad, study hard after going abroad, actively exercise himself and make himself a person with both knowledge and practical ability. Everyone at home is proud of him, hoping to spread the splendid culture of the motherland abroad after going abroad, and never forget that he is from China. After going abroad, facing different cultures and languages, he will certainly encounter many unexpected difficulties, but don't be afraid. Parents, brothers and sisters are his strong pillars. I hope he dares to accept challenges, overcome difficulties, constantly surpass and forge ahead.
