Felicity Miller, a 32-year-old British woman, {#blank#}1{#/blank#} has a Chinese husband, still remembers the {#blank#}2{#/blank#} (excite) when she first learned to use the “red packet” function on WeChat in 2015. She sent and grabbed some red packets in her Chinese family's group. The rule in her family was that the person who grabbed the {#blank#}3{#/blank#} (high) amount sent the next.
