Lion dancing is very popular in Vietnam, but my best friend Anny doesn't enjoy it.
 * My house is near the beach, although I rarely go swimming. (Alternatively: I live near the beach, yet I rarely go swimming.)
 * Nick used to smoke; however, he seems to be in good health.
 * I couldn't sleep; nevertheless, I was tired.
Explanation of Conjunctions:
 * But: This conjunction is used to contrast two ideas. In the first sentence, it highlights the difference between the popularity of lion dancing and Anny's personal preference.
 * Although: This conjunction introduces a contrasting statement that doesn't completely negate the first part. In the second sentence, it shows that despite living near the beach, the speaker doesn't go swimming often.
 * However: Similar to "but," this conjunction introduces a contrasting idea. However, it can sound slightly less forceful than "but." In the third sentence, it shows a contrast between Nick's past smoking habit and his current good health.
 * Nevertheless: This conjunction is used to emphasize a point despite a previous statement. In the fourth sentence, it highlights that even though the speaker couldn't sleep, they were still tired.
