贺卡 (hè kǎ) vs 请柬 (qǐng jiǎn) — use 贺卡 for general greetings or congratulations, while 请柬 is specifically for invitations.

Think of 贺 as 'celebrate' and 卡 as 'card'; imagine a colorful card celebrating your friend's birthday. The 'hè' sounds like 'hey', which you might say when greeting someone, and 'kǎ' can remind you of 'card' in English.

贺卡 is commonly used in both formal and informal settings, but be mindful of the context when choosing the card's design and wording. Common collocations include 生日贺卡 (birthday card) and 祝贺卡 (congratulations card). Avoid using it in overly casual contexts where a simple message might suffice.

Although 贺卡 is not specifically listed in HSK vocabulary, it connects to themes of communication and celebration found in HSK levels 2 and 3. Focus on practicing the related vocabulary for occasions and greetings.

In Chinese culture, sending 贺卡 is an important tradition during major holidays like Spring Festival, where people exchange cards to wish prosperity and happiness. This reflects the value placed on relationships and well-wishing in Chinese society.

A common mistake is using 贺卡 interchangeably with other types of cards, like invitation cards. For example, saying '我给他一个贺卡邀请他' (I gave him a greeting card to invite him) is incorrect; it should be '我给他发邀请函' (I sent him an invitation).
