伴三年走七痒莫忘白头
[bàn sān nián zŏu qī yăng mò wàng bái tóu]
The 'seven-year itch' refers to a critical period for couples during their seven years of marriage. This net name means being with one another through thick and thin over the short and long term and growing old together while remembering the original love in the first three years.
