Meaning:
“稳”means “being stable or secure.” “稳” is a pictographic character consisting of two parts structurally. In the ancient Chinese dictionary Shuo Wen Jie Zi, “稳” is defined as “to separate the husk from the rice and to thresh the grain.” In old times when there was a lack of food, it was often said that “grain in your hand, ease in your mind.” Therefore the character refers to a sense of stability or security. Nowadays netizens use “稳” to describe that something goes well or is a smooth sailing.
Example:
A: 小王参加演讲比赛，还拿了二等奖，怎么看起来不高兴？
Xiǎo Wáng cānjiā yǎnjiǎng bǐsài, hái nále èrděngjiǎng, zěnme kàn qǐlái bu gāoxìng?
How come Xiao Wang had a long face when he won the second prize in the speech contest?
B: 他前几轮成绩一直领先，以为冠军稳了，没想到最后即兴演讲环节太紧张了。
Tā qián jǐ lún chéngjī yīzhí lǐngxiān, yǐwéi guànjūn wěnle, méi xiǎngdào zuìhòu jíxìng yǎnjiǎng huánjié tài jǐnzhāngle
He had been leading in the first few rounds, thinking that the top prize was secured. But he didn’t expect that he would be so nervous for the impromptu speech.
