友好

Both 友好 (yǒuhǎo) and 友善 (yǒushàn) mean "friendly." However, 友好 usually describes a relationship or an atmosphere, while 友善 describes a person's demeanor or attitude. For example, you can say 两国关系友好 (liǎng guó guānxì yǒuhǎo - the relationship between the two countries is friendly), but you would say 她对人很友善 (tā duì rén hěn yǒushàn - she is very friendly to people).

You can use 友好 to describe a friendly relationship, a friendly atmosphere, or a friendly gesture. For example:

• 我们是友好邻居。 (Wǒmen shì yǒuhǎo línjū. - We are friendly neighbors.)
• 他们之间有友好的关系。 (Tāmen zhī jiān yǒu yǒuhǎo de guānxì. - There is a friendly relationship between them.)
• 这次访问是在友好的气氛中进行的。 (Zhè cì fǎngwèn shì zài yǒuhǎo de qìfēn zhōng jìnxíng de. - This visit was conducted in a friendly atmosphere.)

While 友好 primarily describes relationships or atmospheres, you can use it to describe a person as being "friendly" in the context of their general disposition or their interactions with others. However, 友善 (yǒushàn) is more commonly used to describe a person's friendly demeanor. For instance, you could say 他是一个友好的人 (tā shì yī gè yǒuhǎo de rén - he is a friendly person), but 他很友善 (tā hěn yǒushàn - he is very friendly/kind) is often more natural when describing personal traits.

The opposite of 友好 (yǒuhǎo) can depend on the context. If referring to relationships, you might use 敌对 (díduì - hostile/antagonistic). If referring to an atmosphere, 紧张 (jǐnzhāng - tense) or 不和 (bùhé - discordant/at odds) could be used. For unfriendly behavior, 不友好 (bù yǒuhǎo) is a direct negation, meaning "unfriendly."

友好 (yǒuhǎo) is a fairly neutral term and can be used in both formal and informal contexts. You'll hear it in diplomatic statements and casual conversations alike.

Yes, absolutely! In fact, it's very common to use 友好 when talking about relations between countries, organizations, or groups. For example, 两国保持友好关系。 (Liǎng guó bǎochí yǒuhǎo guānxì. - The two countries maintain friendly relations.)

A common phrase is 友好访问 (yǒuhǎo fǎngwèn), which means "friendly visit." Another one is 友好合作 (yǒuhǎo hézuò), meaning "friendly cooperation."

You don't use 友好 directly to say "friend." The word for "friend" is 朋友 (péngyou). However, you can use 友好 to describe a friendly relationship with a friend, like 我们的关系很友好 (wǒmen de guānxì hěn yǒuhǎo - our relationship is very friendly).

No, 友好 (yǒuhǎo) is primarily an adjective. If you want to express the action of being friendly or befriending, you would use other verbs. For example, 和...做朋友 (hé... zuò péngyou - to be friends with...) or 对...很友善 (duì... hěn yǒushàn - to be friendly towards...).

Think of the characters: 友 (yǒu) means friend, and 好 (hǎo) means good. So, literally, "friend-good" helps convey the meaning of friendly, especially in the context of relationships and interactions being good or positive. Remember sentences like 友好国家 (yǒuhǎo guójiā - friendly country) or 友好气氛 (yǒuhǎo qìfēn - friendly atmosphere).
