I feel that going abroad is a betrayal of the motherland, and I have a great ideological burden. What should I do?

The patriotism revealed in your bones is worthy of praise and promotion, and it is also very admirable. From your description, you also understand some truth. Going abroad now really doesn't mean treason. The key is to see where you have more advantages and a higher probability of success. Because you have such a deep patriotism, you will never forget this hot land where you were born and raised. People can serve the motherland without thinking and spirit. As long as you thoroughly understand this truth, the knot in your heart will naturally be solved.
