Before you install, Greasy Fork would like you to know that this script contains antifeatures, which are things there for the script author's benefit, rather than yours.

This script earns commission for the author, for example by rewriting links or providing coupon codes to include a referral or affiliate code. Tác giả script này giải thích: 此提示为GreasyFork代码规范要求含有查券功能的脚本必须添加，实际使用无任何强制跳转，代码可查，请知悉。
