Is "the daughter of Zion" the Christians?

According to **Matthew** *(chapter 21)* the prophecy of **Zechariah 9:9** is fulfilled in Jesus' entry into Jerusalem. This makes Jesus the King of Zion: Matthew 21:1-5 >**1** And when they drew nigh unto Jerusalem, and were come to Bethphage, unto the mount of Olives, then sent Jesus two > disciples, **2** Saying unto them, Go into the village over against > you, and straightway ye shall find an ass tied, and a colt with her: > loose them, and bring them unto me. **3** And if any man say ought > unto you, ye shall say, The Lord hath need of them; and straightway he > will send them. **4** All this was done, that it might be fulfilled > which was spoken by the prophet, saying, **5** Tell *ye* the daughter > of Sion, Behold, thy King cometh unto thee, meek, and sitting upon an > ass, and a colt the foal of an ass. Zechariah 9:9 >Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass. So according to the prophecy of **Zechariah** (and the gospels of **Matthew** and John), those who recognize their King and Savior "arriving, meek, and sitting upon an ass, and a colt the foal of an ass." are identified as the "**daughter of Zion**". To my knowledge, Christians are the only peoples holding this belief, wouldn't that make Christians the "daughter of Zion"?
