Formal:
* 我爱你 (Wǒ ài nǐ) - This is the most common and direct translation, literally meaning "I love you." It's suitable for expressing deep love to a romantic partner, family member, or close friend.
Informal:
* 我喜欢你 (Wǒ xǐhuan nǐ) - This means "I like you" and is a more casual way to express affection. It's often used between friends or romantic partners in the early stages of a relationship.
Romantic:
* 我爱你 (Wǒ ài nǐ) - This is the most common way to express romantic love, but you can also use other expressions like:
* 我深深地爱着你 (Wǒ shēnshēn de ài zhe nǐ) - This means "I love you deeply."
* 我永远爱你 (Wǒ yǒngyuǎn ài nǐ) - This means "I will love you forever."
Other options:
* 你是我的一切 (Nǐ shì wǒ de yīqiè) - This means "You are everything to me."
* 我离不开你 (Wǒ lí bù kāi nǐ) - This means "I can't live without you."
Important note: It's important to be aware of the cultural context when expressing love in Mandarin. In some situations, it might be considered inappropriate to say "I love you" too quickly or to someone who you are not very close to. It's always best to err on the side of caution and use more casual expressions of affection in the beginning.
